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.
