Introduction

The GPM Ground Validation Flight Summaries and Flight Tracks Imagery data set for MC3E provides processed flight summaries from the University of North Dakota and flight track imagery which illustrates the flight tracks of the ER-2 and Citation aircraft used during MC3E.The flight summary data includes sonde maps, radar animations, parameter versus time charts, radar track graphs, and a document concerning aircraft and instrument operational times. The flight tracks imagery includes one animation for May 11, 2011 and 5 minute radar snapshots from the Real Time Mission Monitor (RTMM). This data set is included as reference information in all MC3E ER-2 Navigation and Citation Navigation data set orders.

Campaign

The Mid latitude Continental Convective Clouds Experiment (MC3E) took place in central Oklahoma during the April-June 2011 period. 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 over arching 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 and space-based rainfall retrieval algorithms over land that had never before been available.

File Naming Convention

The flight summary documents are named with the following convention:

Radartrack_graphs_[YYYYMMDD].pdf
[YYYYMMDD]_summary.pdf
[YYYYMMDD]_sondemap.pdf
[YYYYMMDD]_data_all.pdf
YYYYMMDD_TrackRadar_anim.gif

where,

YYYY = year
MM = month
DD = day
gif = "graphics interchange format", an animated image

*Note: Flight summary documents are only available for select days.

The flight tracks imagery is named with the following convention:

[YYYY-MM-DD]_[HH-MM-SS]_MC3E-[RdNm].png

where,

YYYY = year
MM = month
DD = day
HH = hour
MM = minutes
SS = seconds
MC3E = Mid-latitude Continental Convective Clouds Experiment
RdNm = radar name (e.g., KICT)
png = "portable network graphics", a raster graphics file format

The flight track images are composed of NEXRAD radar data displayed on Google Earth images. The radar snapshots are generated by the Real-Time Mission Monitor (RTMM). The flight tracks are displayed over the radar images. The Citation is typically denoted as a blue aircraft with a white flight track while the ER-2 is displayed as a red aircraft with a red flight track. Each flight track image is time stamped (UTC) and is available in 5 minute intervals.
