EOSDIS Data News: July 13, 2018
NASA's Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) published the Global Precipitation Measurement Ground Validation (GPM-GV) Global Flood Monitoring System (GFMS) Flood Maps Iowa Flood Studies (IFloodS) dataset. This dataset contains global flood estimates on a 0.25 degree spatial resolution every 3 hours, from March 26, 2013 through June 30, 2013. These data are provided in support of the IFloodS experiment conducted in eastern Iowa. The goals of the IFloodS campaign were to collect detailed measurements of precipitation at the Earth’s surface using ground instruments and advanced weather radars and to simultaneously collect data from satellites passing overhead. The data are available in netCDF-4 and ASCII formats. Flood map and rain graph files are available in KMZ, JPG, and GIF formats.
NASA's National Snow and Ice Data Center DAAC (NSIDC DAAC) has published data from 22 March 2018 to 16 April 2018 for the dataset IceBridge Sea Ice Freeboard, Snow Depth, and Thickness Quick Look. This dataset is an evaluation product containing derived geophysical data products retrieved over the Arctic sea ice cover using the IceBridge Airborne Topographic Mapper (ATM), Snow Radar, Digital Mapping System (DMS), and KT19 pyrometer.
NSIDC DAAC has published data from 22 March 2017 through 31 March 2017 for the dataset IceBridge Lamont-Doherty Earth Observatory (LDEO) Gravimeter Suite Level 1B (L1B) Geolocated Free Air Gravity Anomalies. This dataset contains gravity measurements taken over Greenland by the LDEO Gravimeter Suite. This dataset is available as part of an early release. An increased Level of Service and more detailed documentation will be available in the future.
NSIDC DAAC has published data through 25 November 2017 for the dataset IceBridge ATM L1B Elevation and Return Strength with Waveforms.
NSIDC DAAC has published data through 25 November 2017 for the dataset IceBridge KT19 IR Surface Temperature. This dataset contains surface temperature measurements of Arctic and Antarctic sea ice and land ice acquired by the Heitronics KT19.85 Series II Infrared Radiation Pyrometer and the NASA ATM instrument onboard the NASA P-3 and NASA DC-8 aircraft.
NSIDC DAAC has published data through 22 November 2017 for the dataset IceBridge Narrow Swath ATM L1B Elevation and Return Strength. This dataset contains spot elevation measurements of Greenland, Arctic, and Antarctic sea ice acquired using the NASA ATM narrow-swath instrumentation.
NSIDC DAAC has published data through 25 November 2017 for the dataset IceBridge ATM L2 Icessn Elevation, Slope, and Roughness. This dataset contains resampled and smoothed elevation measurements of Arctic and Antarctic sea ice, and Greenland, Antarctic Peninsula, and West Antarctic region land ice surface acquired using the NASA ATM instrumentation.

NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC) published the first data from the Africa synthetic aperture radar (AfriSAR) airborne campaign: AfriSAR: Rainforest Canopy Height Derived from Polarimetric Interferometric SAR (PolInSAR) and lidar data, Gabon. This dataset provides estimates of forest canopy height and canopy height uncertainty for study areas in the Pongara National Park and the Lope National Park, Gabon. Two canopy height products are included: 1) Canopy height was derived from multi-baseline PolInSAR data using an inversion of the random volume over ground (RVoG) model and Kapok, an open source Python library. 2) Canopy height was derived from a fusion of PolInSAR and Land, Vegetation, and Ice Sensor (LVIS) lidar data. This dataset also includes various intermediate parameters of the PolInSAR data (including radar backscatter, coherence, and viewing and terrain geometry) which provide additional insight into the input data used to invert the RVoG model and accuracy of the canopy height estimates. The AfriSAR campaign was flown from 2016-02-27 to 2016-03-08. AfriSAR data were collected by NASA, in collaboration with the European Space Agency and the Gabonese Space Agency.
ORNL DAAC published the Atmospheric Carbon and Transport - America (ACT-America) dataset ACT-America: L3 Merged In Situ Atmospheric Trace Gases and Flask Data, Eastern USA. This dataset provides three merged data products acquired during flights over the central and eastern United States as part of the ACT-America project. Two aircraft platforms, NASA's Langley Research Center Beechcraft B200 King Air and NASA's Goddard Space Flight Center C-130H Hercules, were used to collect high-quality in situ measurements across a variety of continental surfaces and atmospheric conditions. The merged data products are composed of continuous in situ measurements of atmospheric carbon dioxide (CO2), methane (CH4), carbon monoxide (CO), ozone (O3), and ethane (C2H6, B200 aircraft only) that were averaged to uniform intervals and merged with trace gas concentrations from discrete flask samples collected with the Programmable Flask Package (PFP) and the aircraft navigation and meteorological variables. These merged data products provide integrated measurements at intervals useful to the modeling community for studying the transport and fluxes of atmospheric CO2 and CH4 across North America.
NASA's Physical Oceanography DAAC (PO.DAAC) released the Aquarius Celestial Sky Microwave Emission Map Ancillary Dataset V1.0. This dataset contains three maps of L-band (wavelength = 21 cm) brightness temperature of the celestial sky ("Galaxy") used in the processing of the NASA Aquarius instrument data. The maps report Sky brightness temperatures in Kelvin gridded on the Earth Centered Inertial (ECI) reference frame epoch J2000. They are sampled over 721 declinations between -90 degrees and +90 degrees and 1441 Right Ascensions between 0 degrees and 360 degrees, all evenly spaced at 0.25 degrees intervals.
PO.DAAC ingested the latest Making Earth System Data Records for Use in Research Environments (MEaSUREs) updates for the Integrated Multi-Mission Ocean Altimeter Data for Climate Research Version 4.2 dataset (Cycles 927 - 941) from B. Beckley. This update covers the period from November 13, 2017 to April 10, 2018.
