EOSDIS Data News: August 2017
NASA's Atmospheric Science Data Center (ASDC), in collaboration with the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Top-of-Atmosphere (TOA) team released the Earth Radiation Budget Experiment (ERBE) ERBE_S10N_WFOV_SF_ERBS_AreaAverageTimeSeries_Edition4 product.
ASDC, in collaboration with the Multi-angle Imaging SpectroRadiometer (MISR) Science team announce the public release of Version 005 of the Airborne Multiangle SpectroPolarimetric Imager (AirMSPI) Level 1B2 data products for the Polarimeter Definition Experiment (PODEX) flight campaign. AirMSPI Level 1B2 products contain radiometric and polarimetric images of clouds, aerosols, and the surface of the Earth. In particular, products contain map-projected data at 8 wavelengths: 355, 380, 445, 470, 555, 660, 865, and 935 nm. The data products include radiance, time, solar zenith, solar azimuth, view zenith, and view azimuth for all spectral bands. Wavelengths for which polarization information is available (470, 660, and 865 nm) also include the Stokes parameters Q and U, as well as degree of linear polarization (DOLP) and angle of linear polarization (AOLP). Q, U, and AOLP are reported relative to both the scattering- and view meridian planes. Files are distributed in HDF-EOS-5 format. This release of AirMSPI data contains all targets acquired during the PODEX flight campaign. PODEX was based out of NASA’s Armstrong (formerly Dryden) Flight Research Center in Palmdale, CA, and focused on clouds and aerosols in and around California. AirMSPI data were acquired from January 14 through February 6, 2013.
NASA's Global Hydrometeorology Resource Center Distributed Active Archive Center (GHRC DAAC) has publlished two additional datasets from the Global Precipitation Management (GPM) Ground Validation (GV) program. "GPM Ground Validation Duke Microwave Radiometer (MWR) Integrated Precipitation and Hydrology Experiment (IPHEx)" data were collected by the MWR, which is a sensitive microwave radiometer that detects the microwave radiance at two frequencies: 23.8 and 31.4 GHz. The measurements are are used to determine the presence of vapor and liquid water molecules in the atmosphere along with other derived parameters. These data were obtained during the IPHEx field experiment, which was held in North Carolina with the goal to characterize warm season orthographic precipitation regimes and the relationship between precipitation regimes and hydrologic processes in regions of complex terrain. These data are available for May 1, 2014 through June 15, 2014 and are in netCDF-3 format.
“GPM-GV Iowa Flood Center (IFC) Rain Gauges IFloodS” data were collected during the Iowa Flood Studies (IFloodS) campaign from April 28 through May 20, 2013 near Shueyville City, Iowa. Four observation sites, each consisting of three tipping bucket rain gauges, collected 5-minute accumulations of precipitation data. The main goal of IFloodS was to evaluate how well the GPM satellite rainfall data can be used for flood forecasting. Specifically, this meant collecting detailed measurements of precipitation at the Earth’s surface using ground instruments and advanced weather radars while simultaneously collecting data from satellites passing overhead.
GHRC DAAC is pleased to announce the public “beta” release of near real-time (NRT) data from the Lightning Imaging Sensor (LIS) on the International Space Station (ISS). Lightning observations and background data files are generated within minutes of observation. A browse web page
