OTD LIS heritage figureThe Lightning Imaging Sensor (LIS) Science Team announces the release of version 2.3.2011 of the LIS/OTD Climatology data sets. The LIS/OTD Climatology data sets consist of gridded climatologies of total lightning flash rates seen by the spaceborne Optical Transient Detector (OTD) and Lightning Imaging Sensor (LIS). These data sets can be ordered from the GHRC DAAC using HyDRO.

GCPEX logoNASA is currently flying an airborne science laboratory above Canadian snowstorms to tackle a difficult challenge facing the upcoming Global Precipitation Measurement (GPM) satellite mission -- measuring snowfall from space. Working with Environment Canada, NASA's GPM Cold-season Precipitation Experiment (GCPEx) is measuring light rain and snow in Ontario from Jan. 17 to Feb. 29.

MC3E logoThe Midlatitude Continental Convective Clouds Experiment (MC3E) took place in central Oklahoma April–May 2011. The experiment was a collaborative effort between the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility and the National Aeronautics and Space Administration’s (NASA) Global Precipitation Measurement (GPM) mission Ground Validation (GV) program.

The field campaign leveraged the unprecedented observing infrastructure currently available in the central United States, combined with an extensive sounding array, remote sensing and in situ aircraft observations, NASA GPM ground validation remote sensors, and new ARM instrumentation purchased with American Recovery and Reinvestment Act funding. The overarching goal was to provide the most complete characterization of convective cloud systems, precipitation, and the environment that has ever been obtained, providing constraints for model cumulus parameterization's and space-based rainfall retrieval algorithms over land that have never before been available.

The GHRC is the archive and distribution center for ground validation data collected during the MC3E Experiment.

The AMSR-E SIPS at the GHRC DAAC would like to announce the availability of AMSR-E near real-time data subscriptions.
With a data subscription, we will push selected data products to a designated computer as soon as the products are generated. In order to receive these products via subscription, you must be a registered LANCE user. Please let us know if you are interested in using our subscription service for AMSR-E near real-time data.

LANCE logoThe AMSR-E SIPS at the GHRC DAAC has implemented incremental daily processing for our AMSR-E near real-time Level 3 daily (Ocean, Land, Snow, Sea Ice ) products. Partial products are created several times per day (currently every 3 hours) using whatever L2 data is available at the time of creation, in order to reduce latency for these products.

These partial products (identified by "P") will be available in the same FTP directories as the complete real-time daily products (identified by "R"). Each new partial product for a given day will have the same file name as the previously-generated one, but will incorporate additional input files. A new partial product can be distinguished by creation time shown in the directory listing. Once the full daily file is available the partial file for that day will be deleted.
