readme.sfc Readme file for BAMEX MIPS surface station data (S.Paech) The MIPS surface station data files are named van_YYYYMMDD_sfc.dat, where: van -> data is from the MIPS van sfc stn YYYY -> year MM -> month DD -> day The data file records, column by column, are: COLUMN VARIABLE ------------------------------------- 0 -> Program Constant 1 -> Year 2 -> Julian Day 3-4 -> Hour & minute, Second.fraction-of-second (UTC) 5 -> (ignore) 6 -> Pressure (mb) 7 -> Temperature (F) 8 -> RH (%) 9 -> Wind Speed at 3m (m/s) 10 -> Wind Direction at 3m (deg) 11 -> Rain Guage 1 (mm) 12 -> Rain Guage 2 (mm) 13 -> Pyranometer (W/m^2) A sample line is given below: (Column #) | 0 1 2 3 4 5 6 7 8 9 10 11 12 13 (data line)| 101,2003,167,2350,13.25,11.67,960.51,81.599,49.013,4.214,156.12,0.254,0.1,628.88 The SFC station instrumentation was mounted on a rack on top of the MIPS Van. The wind monitor was 3m off the ground and approximately 1m off of the roof of the van. Data was collected at 1 sec intervals. Wind directions have been adjusted to take into account the MIPS orientation (as specified in bamexlog.dat) during each deployment. The breaks in the data are when we were moving, or when the system was down. Gauge #2 data was plotted in the sfc data plots. Instruments Used: - RM Young wind monitor - Epply pyranometer - Vaisala BPTB210 barometer with static pressure head - Vaisala platinum resistance temperature detector, and Vaisala Humicap 180 capacitive relative humidity sensor - Texas Electronics raingauges: - gauge 1 - model TR-525I (154mm funnel diam.) - 0.01 inches (0.254 mm) resolution - gauge 2 - model TR-525M (245mm funnel diam.) - 0.1 mm resolution Refer to bamexlog.dat for information regarding MIPS setup during each deployment.
