GHRC has published the GPM Ground Validation Flight Summaries and Flight Tracks Imagery MC3E dataset which provides processed summaries from University of North Dakota including sonde maps, a radar animation, parameter versus time charts, radar track graphs, as well as aircraft and instrument operational times for flights during the Midlatitude Continental Convective Clouds Experiment (MC3E) held in Oklahoma in 2011. The Flight Tracks imagery includes one animation for May 11, 2011 and five-minute snapshots of flight tracks from the Real Time Mission Monitor (RTMM). This dataset will be distributed with the MC3E ER-2 Navigation and the Citation Navigation datasets, which are also part of the GHRC collection of GPM Ground Validation data from MC3E.
The Light Precipitation Evaluation Experiment (LPVEx) took place in the Gulf of Finland during September and October, 2010. Microphysical properties, associated remote sensing observations, and coordinated model simulations of high latitude precipitation systems to drive the evaluation and development of precipitation algorithms for current and future satellite platforms were collected. LPVEx consisted of coordinated aircraft flights within an extensive network of ground-based observations that included three dual-polarization, C-band, Doppler radars, a network of surface weather and sounding stations, several micro-rain radars, and surface rainfall and drop size distribution (DSD) measurements from a large number of rain gauges and disdrometers. LPVEx was a collaborative effort between CloudSat, the GPM Ground Validation (GV) program, the Finnish Meteorological Institute (FMI), Environment Canada (EC), the United Kingdom National Environmental Research Council, Vaisala Inc., and the University of Helsinki (UH).
The 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 
NASA 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.
The 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.
