The GPM Ground Validation Oklahoma Climatological Survey Mesonet MC3E data were collected during the Midlatitude Continental Convective Clouds Experiment (MC3E) in central Oklahoma during the April-June 2011 period. 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 parameterizations and space-based rainfall retrieval algorithms over land that had never before been available. Collected by a network of weather stations, this dataset is composed of 15 minute and 5 minute files with one file per site per day in mts format. Data can be read as ASCII text. Multiple parameters found in this dataset include relative humidity, air temperature, wind speed and direction, precipitation and calibrated soil moisture.

This data set includes soil moisture measurements for the Oklahoma study region. Summary files containing field averages are also provided. This data set is part of the Soil Moisture Experiment 2003 (SMEX03).

This data set contains measurements taken during the Soil Moisture Experiment 2003 (SMEX03) from sensors at Soil Climate Analysis Network (SCAN) stations located in Fort Reno and Little Washita, OK, USA.

This data set combines data for several parameters measured for the Soil Moisture Experiment 2003 (SMEX03). This study was conducted between 2 July 2003 and 17 July 2003 in the Little Washita watershed in Oklahoma, USA.

The GPM Ground Validation NOAA Parsivel MC3E dataset was collected in central Oklahoma during the Midlatitude Continental Convective Clouds Experiment (MC3E) from April 5, 2011 through June 6, 2011. The NOAA Parsivel dataset includes processed data consisting of either moment data (e.g., reflectivity and rain rate estimates) or raindrop number concentration estimates; the data provided a reference reflectivity to calibrate the S-band profiler during the experiment. The moment data includes 1-minute resolution estimates of rain rate, reflectivity, and other parameters related to the health of the Parsivel instrument. The raindrop number concentration data are also at 1-minute resolution and are the result of converting the observed raindrop passing the sensor into the number of raindrops expected in a unit volume per diameter interval. Both the moment data and the number concentration data were saved in daily files in ASCII format. Daily images were also generated from the Parsivel observations and contain the 1-minute reflectivity, rain rate, and number concentration N(D); browse images are saved in TIF format.

The GPM Ground Validation NOAA Surface Meteorological Station MC3E dataset was collected at the NOAA Southern Great Plains Facility for the Midlatitude Continental Convective Clouds Experiment (MC3E) and includes measurements of wind speed, wind direction, temperature, humidity and precipitation. 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 parameterizations and space-based rainfall retrieval algorithms over land that had never before been available. The instruments gathering this data were respectively a propeller wind monitor located 10 meters above the ground, a temperature and humidity sensor at the ground, and a tipping rain gauge at the ground. These data were collected from April 5, 2011 to June 7, 2011.
