Wallops Island Balloon Technology: Can’t see the Repository for the DocumentsAndrea Japzon & Nikkia Anderson
Since the Wallop’s Balloon Technology documents repository began approximately 9 years ago, the Goddard Library has become increasingly involved in developing digital archiving capabilities. The Library developed the Digital Archiving System (DAS) which is a prototype infrastructure for creating a combined metadata repository that allows metadata for heterogeneous digital objects to be searched with a single search mechanism and presented in a single results page. With this, the opportunity has been presented to expand the...
Thinner bark increases sensitivity of wetter Amazonian tropical forests to fireAnn Carla Staver, Paulo M. Brando, Jos Barlow, Douglas C. Morton, C.E. Timothy Paine, Yadvinder Malhi, Alejandro Araujo Murakami & Jhon Pasquel
Understory fires represent an accelerating threat to Amazonian tropical forests and can, during drought, affect larger areas than deforestation itself. These fires kill trees at rates varying from < 10 to c. 90% depending on fire intensity, forest disturbance history and tree functional traits. Here, we examine variation in bark thickness across the Amazon. Bark can protect trees from fires, but it is often assumed to be consistently thin across tropical forests. Here, we show...

Grad-Shafranov equation: MHD simulation of the new solution obtained from the Fadeev and Naval modelsArian Ojeda Gonzalez, Leandro Nunes Dos Santos, José Juan González-Avilés, Victor De La Luz & Pablo Rubén Muñoz-Gutberlet
This article aims to obtain a new analytical solution of a specific form of the Grad-Shafranov (GS) equation using Walker's formula. The new solution has magnetic field lines with X-type neutral points, magnetic islands and singular points. The singular points are located on the x-axis. The X-points and the center of the magnetic islands do not appear on the x-axis an island appears at $z>0$ and the other two at $z<0$. The aforementioned property allows...
A survey of small-scale waves and wave-like phenomena in Jupiter's atmosphere detected by JunoCamGlenn 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...
High-resolution (1.3kmx1.3-km) WRF-Chem output driven with the Hestia, and two nightlight-based fossil fuel emission products over the LA basin from 5/15/2020-6/15/2020S. Feng, T. Lauvaux, T. Oda, M.O. Román, Z. Wang, S. Maksyutov & V.L. Kalb
This high-resolution WRF-Chem model output is driven with three different fossil fuel emission products: Hestia (Gurney et al., 2018), and two nightlight-based CO2 emission data using the same setup as Feng et al (2016). The nightlight data products are based on DMSP (Oda and Maksyutov, 2011) and NASA’s Black Marble Nighttime Lights Product Suite (VNP46) (Román et al., 2018; Oda et al. 2020). This sensitivity atmospheric modeling experiment demonstrates the utility of CO2 mapping, helping...
Dataset of Constraining fossil fuel CO2 emissions from urban area using OCO-2 observations of total column CO2X. Ye, T. Lauvaux, E.A. Kort, T. Oda, S. Feng, J.C. Lin, E.G. Yang & D. Wu
Satellite observations of the total column dry-air CO2 (XCO2) are expected to support the quantification and monitoring of fossil fuel CO2 (ffCO2) emissions from urban areas. We evaluate the utility of the Orbiting Carbon Observatory 2 (OCO-2) XCO2 retrievals to optimize whole-city emissions, using a Bayesian inversion system and high-resolution transport modeling. The uncertainties of constrained emissions related to transport model, satellite measurements, and local biospheric fluxes are quantified. For the first two uncertainty sources,...
