readme.mpr Readme file for IHOP MIPS Microwave Profiling Radiometer (MPR) data (S.Paech) The MPR data contain atmospheric profiles of temperature, water vapor and cloud liquid at 15 minute intervals. Data files are in a condensed format and are named mpr_YYYYMMDD.dat where: YYYY -> year MM -> month DD -> day The data records are as follows: COLUMN VARIABLE ----------------------------------------------------------------------------------------------------- 1 -> identifies the profile as temperature (T), water vapor (V) or cloud liquid water (L). 2-3 -> measurement date and time (UTC) 4-6 -> surface conditions as measured at/by the MPR (temperature, relative humidity and pressure) . 7 -> Tir: Infrared thermometer temperature (cloud base temp) (K) 8 -> the presence or absence of rain is reported as Y (yes) or N (no) 9 -> Vint: integrated vapor (cm) 10 -> Lqint: integrated liquid (mm) 11-57 -> profile data at each height (km): 100m spacing to 1 km, 250m spacing above, to 10 km.
