Beagle 2 was an exobiology lander designed to look for isotopic and compositional signs of life on Mars, as part of the European Space Agency Mars Express (MEX) mission. The 2004 recalculation of the original landing ellipse from a 3-sigma major axis from 174 km to 57 km,...

Data from: From lidar waveforms to vegetation products: 7380 km2 of high-resolution airborne and simulated GEDI data over Sierra Nevada, California

Antonio Ferraz, Fabian Schneider, Kathryn Bormann, Sassan Saatchi, David Schimel & Thomas Painter
Vegetated ecosystems have complex three-dimensional (3D) canopy structures with diverse plant type assemblages, crown architectures and historical disturbances. Vegetation structure changes dramatically with strong topographic, edaphic and climate gradients. Airborne lidar remote sensing has the potential to measure fine-scale 3D proprieties of forests with limited temporal and spatial coverage limitations due to prohibitively cost. Here, we present a composite high-resolution airborne lidar dataset covering 7380 km2 over the Sierra Nevada, California, that has been calculated...

From these spectra, accurate and precise column-averaged abundances of atmospheric constituents including CO2, CH4, N2O, HF, CO, H2O, and HDO, are retrieved. This is the GGG2020 data release of observations from the TCCON station at Park Falls, Wisconsin, USA

Topographic data to support the analysis of error and uncertainty that degrade topographic corrections of remotely sensed data

Jeff Dozier, Latha Baskaran & Thomas H. Painter
Eight zip files comprise the dataset. Each set of files (Carson, Himachal Pradesh, Wrangell) contains digital elevation data for the same area but from different data sources. The finer-resolution data (3m for Carson, 8m for Himachal Pradesh, 5m for Wrangell) were derived, respectively, from airborne lidar, structure-from-motion from fine-resolution commercial satellite imagery, and airborne interferometric synthetic aperture radar. The coarser-resolution but globally available data are from the Copernicus DEM and the NASADEM (NDEM). The NASADEM...

Full WRF-Chem Ensemble model output in support of the CMS-WRF-CO2 system for 2010

S. Feng, T. Lauvaux, M.P. Butler, J. Liu, K.W. Bowman & K.J. Davis
Quantifying the uncertainty of inversion-derived carbon dioxide (CO2) surface fluxes and attributing the uncertainty to errors in either flux or atmospheric transport simulations continue to be challenges in the characterization of surface sources and sinks of CO2. Despite recent studies inferring fluxes using higher-resolution modeling systems, the utility of regional-scale models remains unclear compared to existing coarse-resolution global systems. Here we present an off-line coupling of the mesoscale Weather Research and Forecasting (WRF) model to...

Ambient and nitrogen environment friction data for various materials and surface treatments for space applications

Azhar Vellore, Sergio Romero Garcia, Duval Johnson & Ashlie Martini
A multivariate tribological evaluation of candidate materials, surface treatments and dry film lubricants is necessary for design of moving mechanical components that function reliably in extreme conditions, including for long duration space missions. In this study, linear reciprocating or unidirectional sliding friction data was collected using ball-on-flat tests. The balls were hardened 440C stainless steel (either uncoated or sputtered with MoS2) and flat surfaces were 440C stainless steel, Nitronic 60 stainless steel or Ti6Al4V titanium...

Digital holographic microscope recordings of passive motion of small particles

Christian Lindensmith, Jay Nadeau & Devan Rouzie
Digital holographic microscopy provides the ability to observe throughout a volume that is large compared to its resolution without the need to actively refocus to capture the entire volume. This enables simultaneous observations of large numbers of small objects within such a volume. We have constructed a microscope that can observe a volume of 0.4 x 0.4 x 1.0 µm with submicrometer resolution (in xy) and 2 µm resolution (in z) for observation of microorganisms...

Retreat of Humboldt Gletscher, North Greenland, driven by undercutting from a warmer ocean

Eric Rignot, Lu An, Nolwenn Chauché, Mathieu Morlighem, Seongsu Jeong, Michael Wood, Jeremie Mouginot, Joshua Willis, Ingo Klaucke, Wilhelm Weinrebe & Andreas Muenchow
Humboldt Gletscher is a 100-km wide, slow-moving glacier in north Greenland which holds a 19-cm global sea level equivalent. Humboldt has been the fourth largest contributor to sea level rise since 1972 but the cause of its mass loss has not been elucidated. Multi-beam echo sounding data collected in 2019 indicate a seabed 200 m deeper than previously known. Conductivity temperature depth (CTD) data reveal the presence of warm water of Atlantic origin at 0°C...

Habitat use as an indicator of adaptive capacity to climate change

Claire Teitelbaum, Alexej Siren, Ethan Coffel, Jane Foster, Jacqueline Frair, Joseph Hinton, Radley Horton, David Kramer, Corey Lesk, Colin Raymond, David Wattles, Katherine Zeller & Toni Lyn Morelli
Aim: Populations of cold-adapted species at the trailing edges of geographic ranges are particularly vulnerable to the negative effects of climate change from the combination of exposure to warm temperatures and high sensitivity to heat. Many of these species are predicted to decline under future climate scenarios, but they could persist if they can adapt to warming climates either physiologically or behaviorally. We aim to understand local variation in contemporary habitat use and use this...

Grounding line of Denman Glacier, East Antarctica from satellite radar interferometry

Virginia Brancato, Eric Rignot, Pietro Milillo, Mathieu Morlighem, Jeremie Mouginot, Lu An, Bernd Scheuchl, Seong Su Jeong, Paola Rizzoli, Jose Luiz Bueso Bello & Pau Prats-Iraola
Grounding line, elevation changes, and melt rates maps of Denman Glacier, East Antarctica. Using satellite radar interferometry from the COSMO-SkyMed mission we map the grounding line of Denman Glacier, East Antarctica. We complement these data with some historical interferometric radar acquisition from the European satellite ERS-1/2. We present new maps of elevation changes on the grounded and floating portions of Denman Glacier obtained by temporally differencing TanDEM-X Digital Elevation Models.

UCL CPOM CryoSat2 derived Dynamic Ocean Topography 2011-2021

Harold Heorton
The ocean surface height is constantly varying under the effects of gravity, density and the Earth's rotation. Information on the Ocean surface elevation in polar regions is available from the CryoSat2 Radar instrument. We compare ocean surface elevation to a static geoid product (GOCO03s) to give the part of the ocean surface elevation accountable due to surface currents, the Dynamic Ocean Topography (DOT). This measurement is smoothed over 100 km and gives monthly surface currents....

UCL CPOM CryoSat2 Polar Ocean Significant Wave Height 2011-2019

Harold Heorton
We present the significant ocean surface wave heights in the Arctic and Southern Oceans from CryoSat-2 data. We use a semi-analytical model for an idealised synthetic aperture satellite radar or pulse-limited radar altimeter echo power. We develop a processing methodology that specifically considers both the Synthetic Aperture and Pulse Limited modes of the radar that change close to the sea ice edge within the Arctic Ocean. All CryoSat-2 echoes to date were matched by our...

Data from: Tropical tree size-frequency distributions from airborne lidar

Antonio Ferraz, Sassan Saatchi, Marcos Longo & David Clark
Tropical rainforest canopies, where stems and crowns reside, are hotspots of biological diversity, mediate the global biochemical processes and are the interface between organic nature and the atmosphere. Ecosystem functions such as growth, competition and mortality, depend on the spatial arrangement of tree crowns that varies significantly across forest types and disturbance gradients. The exact nature and function of tropical tree canopies are not well known. Field inventories often focus on measuring the horizontal component...

Annual Ice Velocity of the Greenland Ice Sheet (1991-2000)

Jeremie Mouginot, Eric Rignot, Bernd Scheuchl, Romain Millan & Michael Wood
We derive surface ice velocity using data from 16 satellite sensors deployed by 6 different space agencies. The list of sensors is given in the Table S1. The SAR data are processed from raw to single look complex using the GAMMA processor (www.gamma-rs.ch). All measurements rely on consecutive images where the ice displacement is estimated from tracking or interferometry (Joughin et al. 1998, Michel and Rignot 1999, Mouginot et al. 2012). Surface ice motion is...

Celso De Melo, Brandon Rothrock, Prudhvi Gurram, Oytun Ulutan & B.S. Manjunath
Building successful collaboration between humans and robots requires efficient, effective, and natural communication. This dataset supports the study of RGB-based deep learning models for controlling robots through gestures (e.g., “follow me”). To address the challenge of collecting high-quality annotated data from human subjects, synthetic data was considered for this domain. This dataset of gestures includes real videos with human subjects and synthetic videos from our custom simulator. This dataset can be used as a benchmark...

Surface deformation associated with fractures near the 2019 Ridgecrest earthquake sequence

Xiaohua Xu, David T. Sandwell, Lauren A. Ward, Chris W. D. Milliner, Bridget R. Smith-Konter, Peng Fang & Yehuda Bock
Contemporary earthquake hazard models hinge on an understanding of how strain is distributed in the crust and the ability to precisely detect millimeter-scale deformation over broad regions of active faulting. Satellite radar observations revealed hundreds of previously unmapped linear strain concentrations (or fractures) surrounding the 2019 Ridgecrest earthquake sequence. We documented and analyzed displacements and widths of 169 of these fractures. Although most fractures are displaced in the direction of the prevailing tectonic stress (prograde),...

Raw holograms frames of Bacillus Subtilis at different temperatures

Nikki Johnston, Megan Dubay, Mark Wronkiewicz, Jake Lee, Christian Lindensmith & Jay Nadeau
We describe a system for high-temperature investigations of bacterial motility using a digital holographic microscope completely submerged in heated water. Temperatures above 90 ºC could be achieved, with a constant 5 ºC offset between the sample temperature and the surrounding water bath. Using this system, we observed active motility in Bacillus subtilis up to 66 ºC. As temperatures rose, most cells became immobilized on the surface, but a fraction of cells remained highly motile at...

High-latitude Input for Meso-scale Electrodynamics (HIME)

Dogacan Su Ozturk
High-latitude Input for Meso-scale Electrodynamics: HIME, is a new framework that is developed to account for the local meso-scale electric field variability in a global I-T model, so that their role during certain intervals and locations can be analyzed. This data set consists of local 2D electric field estimates from PFISR (provided in 20170302.002_lp_1min-cal_2dVEF_001001_NoLonely-geo600km.h5), and HIME generated drivers. These drivers were generated by first calculating the electric potentials with Forward Euler formula from PFISR estimates...

A survey of small-scale waves and wave-like phenomena in Jupiter's atmosphere detected by JunoCam

Glenn Orton, Fachreddin Tabataba-Vakili, Gerald Eichstaedt, John Rogers, Candice Hansen, Thomas Momary, Andrew Ingersoll, Shawn Brueshaber, Michael H. Wong, Amy Simon, Leigh Fletcher, Michael Ravine, Michael Caplinger, Dakota Smith, Scott Bolton, Stephen Levin, James Sinclair, Chloe Thepenier, Hamish Nicholson & Abigail Anthony
In the first 20 orbits of the Juno spacecraft around Jupiter, we have identified a variety of wave-like features in images made by its public-outreach camera, JunoCam. Because of Juno’s unprecedented and repeated proximity to Jupiter’s cloud tops during its close approaches, JunoCam has detected more wave structures than any previous surveys. Most of the waves appear in long wave packets, oriented east-west and populated by narrow wave crests. Spacing between crests were measured as...
