 NASAGHRC DAAC published the Hurricane and Severe Storm Sentinel (HS3) Flight Reports dataset. The HS3 Flight Reports dataset provides information about flights flown by the WB-57 and Global Hawk aircrafts during the Hurricane and Severe Storms Sentinel (HS3) campaign from 2012 to 2014. The HS3 Flight Reports include flight number, flight time (beginning and end), location of the flight (flight segments), flight purpose, and comments regarding the flight and mission. In addition, some reports include corresponding satellite imagery, maps of flight tracks...

The Global Hydrology Resource Center (GHRC) DAAC has published two additional datasets from the Hurricane and Severe Storm Sentinel (HS3) mission.

  • The HS3 Global Hawk Advanced Vertical Atmospheric Profiling System (AVAPS) Dropsonde System dataset provides data from the AVAPS dropsondes built by the National Center for Atmospheric Research (NCAR) and used as the dropsonde system for the Global Hawk aircraft during the HS3 campaign. AVAPS dropsondes provide in-situ, high-vertical resolution measurements of atmospheric variables including pressure, temperature,...

On December 15, the AMSR-E SIPS at GHRC DAAC announced the availability of three near real-time AMSR2 Daily Sea Ice data sets via NASA’s Land Atmosphere Near real-time Capability for EOS (LANCE). These data sets are generated incrementally in near real-time, as data are acquired from the AMSR2 instrument on the Japanese Aerospace Exploration Agency (JAXA) GCOM-W1 satellite. LANCE AMSR2 GIBS Sea Ice imagery will be available in Worldview very soon.

You can access the data at GHRC's LANCE AMSR2...

GHRCDAAC published the GRIP Hurricane Imaging Radiometer (HIRAD) V1 dataset. This dataset contains brightness temperatures at 5 GHz and is an update to the earlier Version 0 GRIP HIRAD dataset. The data were collected during the Genesis and Rapid Intensification Processes (GRIP) experiment in 2010 for Hurricanes EARL and KARL. HIRAD is a hurricane imaging, single-pol passive C-band radiometer with both cross-track and along-track resolution that measures strong ocean surface winds through heavy rain from an aircraft or space-based platform. Its swath width is approximately 60 degrees in either direction.

IPHEX logoThe Global Hydrology Resource Center (GHRC) published two datasets from the Global Precipitation Measurement (GPM) mission ground validation (GV) Integrated Precipitation and Hydrology Experiment (IPHEx): Cloud Radar System (CRS) and Total Sky Imager. The IPHEx experiment was conducted in North Carolina during the months April-June 2014. The Cloud Radar System dataset provides high-resolution profiles of reflectivity and Doppler velocity at aircraft nadir along the...
