Data Format Descriptions
California Land-Falling Jets Experiment Processed Surface Meteorology
This README file gives information about the surface met data for the Caljet '98 project. 1) File Nomenclature: The filename consists of twelve characters. The first three represent the site acronym, characters four and five represent the year, characters six through eight represent the month, and the extension represents the averaging period which is either 2-minute data, 10-minute data, 15-minute data, and hourlydata. The format is therefore: sssyymmm.aaa where sss is site name, yy is year, mmm is month, and aaa is averaging period. All sites have 2-min averaged and hourly averaged data for each month, with the exception of San Clemente Island (SCE) which has 10-min averaged data, and Farallon Is which has 15-min averaged data instead of 2-min. There were thirteen sites for the Caljet '98 project. These sites, along with their three-letter acronym are listed as follows: Site Name Three-letter Acronym 1) Bodega Bay BBY 2) Crescent City CRC 3) Cazadero CZD 4) Eureka ERK 5) Farallon Is FNI 6) Goleta GLA 7) Newport NPT 8) Point Arena PAA 9) Point Piedras Blancas PPB 10) San Clemente Is SCE 11) Santa Catalina Is SCL 12) Tustin TTN 13) Los Angeles (USC) USC 2) Project Duration: The Caljet '98 Project officially started November 07, 1997 and ended March 31, 1998. 3) Data Parameters: The surface meteorological data collected/derived during this project are listed, along with their unit of measure, as the following: a) pressure (mb) b) temperature (C) c) relative humidity (%) d) wind speed (m/s) e) wind direction (DEG) f) solar radiation (W/m**2) g) net radiation (W/m**2) h) mixing ratio (g/kg) h) *precipitation (mm) i) *peak gust (m/s) * These parameters are not included in the Farallon Is data set. 4) Data File Formats a) 02-min or 10-min (or 15-min) data files: Each file has four lines of header which can be read as a character string. The rest of the file contains data in the following format: yr,month,day,Julian Day,monthly index,hour (UTC),min,pr,t,rh,ws,wd,sol,net,mr, precip,peak gust. format(3(i2,1x),i3,1x,i5,1x,i2,i2,1x,f7.2,1x,2(f5.1,1x),f4.1,1x,i3,1x,2(f6.1,1x),f6.2,1x,f7.3,1x,f4.1) b) hourly-averaged data files: Each file has four lines of header which can be read as a character string. The rest of the file contains data in the following format: yr,month,day,Julian Day,monthly index,start hr (UTC),start min,end hr (UTC), end min,pr,t,rh,ws,wd,sol,net,mr,precip,peak gust format(3(i2.2,1x),i3.3,1x,i5.5,1x,2(i2.2),1x,2(i2.2),1x,f7.2,1x,2(f5.1,1x), f4.1,1x,i3.3,1x,2(f6.1,1x),f6.2,1x,f6.2,1x,f4.1) 5) Parameter Flags: a) pressure -99.99 b) temperature -99.9 c) relative humidity -99.9 d) wind speed -9.9 e) wind direction -99 f) solar radiation -999.9 g) net radiation -999.9 h) mixing ratio -99.99 i) precipitation -99.99 j) peak gust -9.9
