NASA's Atmospheric Science Data Center (ASDC), in collaboration with the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) mission announces the release of the CAL_IIR_L1- Standard-V2-00 data product. Version 2.00 of the Imaging Infrared Radiometer (IIR) Level 1 product is the first major revision since the initial release in 2006. The calibration procedure has been adjusted to reduce known small seasonal calibration biases in the Northern Hemisphere, which were caused by thermal drifts synchronized with the elapsed time since the night-to-day transition. The product is available from June 13, 2006 to current. The Version 1 standard and expedited data products will continue to be generated and provided to the public. Information about this data product, including data availability, user documentation and quality statements, relevant links, sample read software, and tools for working with the data, etc. can be found at the following ASDC link: https://eosweb.larc.nasa.gov/project/calipso/calipso_table.

ASDC and NASA's Jet Propulsion Laboratory (JPL) announces the public release of Version 006 of the Airborne Multiangle SpectroPolarimetric Imager (AirMSPI) Level 1B2 data products for the ObseRvations of Aerosols above CLouds and their intEractionS (ORACLES) flight campaign. AirMSPI flies in the nose of NASA's high-altitude ER-2 aircraft. The instrument was built by JPL and the University of Arizona and is aimed primarily at remote sensing of the amounts and microphysical properties of aerosols and clouds. AirMSPI Level 1B2 products contain radiometric and polarimetric images of clouds, aerosols, and the surface of the Earth. This release of AirMPSI data contains all targets acquired during the ORACLES flight campaign, including the check-out and transit flights. ORACLES was based out of Walvis Bay, Namibia and focused on the South Atlantic Ocean off the coast of Namibia and Angola. AirMSPI was acquired from July 28 to October 6, 2016. Information about these products, details about product quality, and mechanisms to access the data can be found under AirMSPI Data and Information at the ASDC website. Please check back often as new products are continuing to be added and made available for ordering.

NASA's Global Hydrology Resource Center (GHRC) DAAC has published the Hurricane and Severe Storm Sentinel (HS3) Scanning High-Resolution Interferometer Sounder (S-HIS) dataset. The S-HIS instrument measures emitted thermal radiances that are used to obtain temperature and water vapor profiles of the Earth's atmosphere in clear-sky conditions. Due to the S-HIS scanning capability, the instrument provides 2 km resolution (at nadir) across a 40 km wide ground swath when flown at an altitude of 20 km onboard the NASA Global Hawk unmanned aircraft. S-HIS data were collected during the 5-week HS3 field campaign study periods in the 2012 to 2014 Atlantic hurricane seasons.
NASA's National Snow and Ice Data Center (NSIDC) DAAC would like to announce a change to data access for the MEaSUREs Annual Greenland Outlet Glacier Terminus Positions from SAR, Version 1 data set. Data access is now solely through our primary portal at: https://n5eil01u.ecs.nsidc.org/MEASURES/NSIDC-0642.001/. File level spatial and temporal metadata have been added to aid in searching the data.
NSIDC DAAC has also made updated Soil Moisture Active Passive (SMAP) Level-4 Products. There are several changes to the Level 4 soil moisture and carbon data. SMAP observations are now assimilated in Eastern Europe, the Middle East, and East Asia due to expanded coverage of the brightness temperature scaling parameters. An improved version of the model-only Nature Run (NRv4.1) simulation is used to derive the brightness temperature scaling parameters, the model soil moisture initial conditions, and the soil moisture climatology. Level 4 carbon model now uses dynamic 8-day fPAR inputs obtained from the latest (Collection 6) Moderate Resolution Imaging Spectroradiometer (MODIS) fPAR record at 500 m resolution.
