readme.mpr Readme file for PECAN Microwave Profiling Radiometer (MPR) data There is 1 MPR data file for each IOP, of the format IOP_XXX.csv where: XXX -> IOP Number csv -> file extension A description of the file is given below -------------------------------------------------------------------------------------------------------------------- 1.) IOP_XXX.csv data, Where XXX is the IOP number These files contain (in a condensed format) atmospheric profiles of temperature, water vapor, relative humidity and cloud liquid at 1 minute intervals. The data, column by column, is as follows: Column 0 -> identifies the record number 1 -> measurement date and time (UTC) 2 -> identifies profile as profile as temperature (T) -> 11 water vapor (V) -> 12 relative humidity (R) -> 13 cloud liquid water (L) -> 14 3-5 -> surface conditions as measured at/by the MPR (temperature, relative humidity and pressure). 6 -> Tir: Infrared thermometer temperature (cloud base temp) (K) 7 -> the presence or absence of rain: reported as Y (yes) or N (no) 8 -> Vint: integrated vapor (cm) 9 -> Lqint: integrated liquid (mm) 10-56 -> profile data at each height (km): 100m spacing to 1 km, 250m spacing above, to 10 km. An example is given below: Record,Date/Time,10,Tamb(K),Rh(%),Pres(mb),Tir(K),Rain,Vint(cm),Lqint(mm), 0.00, 0.10, 0.20, 0.30, 0.40, 0.50, 0.60, 0.70, 0.80, 0.90, 1.00, 1.25, 1.50, 1.75, 2.00, 2.25, 2.50, 2.75, 3.00, 3.25, 3.50, 3.75, 4.00, 4.25, 4.50, 4.75, 5.00, 5.25, 5.50, 5.75, 6.00, 6.25, 6.50, 6.75, 7.00, 7.25, 7.50, 7.75, 8.00, 8.25, 8.50, 8.75, 9.00, 9.25, 9.50, 9.75,10.00 1,03/13/06 00:02:20,11,302.3, 13.3, 802.9,223.2,N, 0.89, 0.04,302.3,298.7,299.2,299.0,298.0,297.2,296.4,295.5,294.5,294.1,293.5,291.9,289.8,286.7,282.7,277.9,272.0,267.0,264.9,263.7,262.8,261.8,259.4,258.8,258.3,257.3,256.4,254.6,253.3,252.0,249.9,247.9,246.0,244.1,242.6,241.9,240.4,238.1,236.2,234.3,232.4,230.7,228.2,226.0,223.5,220.8,218.6 2,03/13/06 00:02:20,12,302.3, 13.3, 802.9,223.2,N, 0.89, 0.04, 3.74, 0.45, 0.37, 0.30, 0.25, 0.21, 0.18, 0.16, 0.15, 0.14, 0.16, 0.17, 0.38, 0.92, 1.65, 3.92,12.67,24.60,32.22,42.66,46.71,48.58,49.31,46.09,46.34,48.43,48.61,48.47,47.04,45.50,44.27,40.11,35.63,15.16, 2.46, 0.63, 0.23, 0.07, 0.02, 0.01, 0.03, 0.02, 0.01, 0.01, 0.00, 0.02, 0.02 3,03/13/06 00:02:20,13,302.3, 13.3, 802.9,223.2,N, 0.89, 0.04, 12.9, 1.9, 1.5, 1.3, 1.1, 1.0, 0.9, 0.8, 0.8, 0.8, 0.9, 1.1, 2.7, 7.8, 18.0, 58.5,100.0,100.0,100.0,100.0,100.0,100.0,100.0,100.0,100.0,100.0,100.0,100.0,100.0,100.0,100.0,100.0,100.0,100.0,100.0,100.0, 64.2, 23.7, 8.9, 4.3, 15.7, 16.7, 13.3, 17.5, 6.4, 35.0, 47.0 4,03/13/06 00:02:20,14,302.3, 13.3, 802.9,223.2,N, 0.89, 0.04, 0.00, 0.00, 0.00, 0.00, 0.00, 0.01, 0.01, 0.01, 0.01, 0.01, 0.01, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.01, 0.01, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.01, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.01, 0.00, 0.00, 0.00 Data Issue: The MPR experienced issues at times throughout the project with spikes in the water vapor and rh measurements. Data has been processed and cleaned up. We left much of the bad water vapor and rh measurements in there since the temperature measurements were good for those periods.
