The ocean absorbs about 25% of the atmospheric CO2 emitted by human activities. The estimate of ocean CO2 uptake provides an important constraint on the global carbon budget. This dataset includes monthly distribution of CO2 fugacity and ocean-atmosphere CO2 flux in 1x1 degree grids for the 1985-2019 period estimated using a neural network. The dataset will be updated annually to include the most recent CO2 observations.

The Laboratory of Meteorology, Institute for Space-Earth Environmental Research, Nagoya University, has been performing daily high-resolution weather simulations using the cloud resolving storm model CReSS (Cloud Resolving Storm Simulator). To demonstrate how well the current model can simulate real-world weather, the results of the simulations are mainly intended for experts. This dataset is the original data from that simulation, shown on the Web page "CReSS Daily Simulation". The area of calcuration is about 2300km by...

The NARO2017 regional climate change scenario has agro-meteorological elements such as solar radiation, relative humidity, and surface wind speed, which are few examples in common climate scenarios across fields so far. The variance of climate model output with small daily and annual fluctuations is matched by observational statistics. It is a climate scenario that can certainly apply with climate extremes. Attention!!: In principle, this data set is not available for the previous version. If you...

To realize an autonomous winter time-series observation of the water column in a coastal polynya, we developed a new profiler platform for a fixed location. We deployed a tethered mid-depth float, whose buoyant capability was significantly enhanced by increasing bladder volume. The float system obtained profiles of temperature and salinity over an entire winter in the Cape Darnley Polynya, East Antarctica.The profiling float used in this study sinks and rises by changing its buoyancy. It...

Chlorophyll a concentration is the most common indicator of phytoplankton biomass, basically regulated by macro-nutrients and light intensity. Therefore, long term monitoring of these parameters gives us fundamental information on ecosystem changes with climate changes. As part of the monitoring programs of the Japanese Antarctic Research Expedition (JARE), chlorophyll a concentration and macro-nutrients (nitrate, nitrite, phosphate and silicate) have been measured on board icebreakers Fuji and Shirase from JARE-14 in the 1972/73 season and from...

The product includes 10-day means of global gross primary production (GPP), net ecosystem exchange (NEE), and ecosystem respiration (RECO) of 1999 to 2019 in 0.1x0.1 degree spatial resolution. Random Forest (RF) was used to upscale observations of FLUXNET 2015 (https://fluxnet.fluxdata.org/data/fluxnet2015-dataset/fullset-data-product/) to the globe from 60°S to 80°N. The daily GPP was extracted from GPP_NT_VUT_REF, NEE from NEE_VUT_REF and RECO from RECO_NT_VUT_REF in the FULLSET of FLUXNET 2015. Predictor variables include leaf area index (LAI), fraction...

We analyzed the chemical compositions of dust and sea-salt particles in the EPICA Dome C (EDC) ice core during 26-7 kyr BP using an ice-sublimation technique, and compared the results with existing data of the Dome Fuji (DF) ice core. Combined with ion concentration data, our data suggested similar sea-salt fluxes in both cores and significantly lower dust flux in the EDC core. The differences in modal size and aspect ratio of dust particles between...
