Constant Pressure Imagery [NCAR/RAL]


This dataset contains 12-hourly constant pressure maps over the United States generated from twice-daily sonde launched from weather stations within the ICE-L region. For each weather station, the maps report temperature (°C) to the upper left, dewpoint depression (°C) below it, altitude of the pressure level (decameters) to the upper right, and a wind barb representing the wind speed and direction. The levels included are 150, 200, 250, 300, 500, 700, 800, and 850 mb (millibars). The imagery was generated in real-time by NCAR/RAL during the ICE-L field project and covers the time span from 2007-10-24 12:00:00 to 2007-12-03 12:00:00. The imagery is in GIF format.
