README.TXT - Description of WSU LAR Grid 3 Tall Tower Data Files Excluding Sonic Anemometers

In addition to the four 3-d sonic anemometers, four IRGAs, and six 2-3 sonic anemometers 
listed above, WSU also made measurements of non-aspirated air temperature and relative 
humidity at 2, 12, 20, 25, 30, 45, 52, and 60 m heights using Campbell Scientific HMP45C 
sensors and at 4, 8, 16, 35, and 40 m heights using Campbell Scientific  HC2S3 sensors. 
Measurements of atmospheric pressure (2 and 60 m), infrared radiometer (30 m), and soil heat 
flux (6 and 12 cm) were also made.

The air temperature, relative humidity, wind speed and direction, net radiation, air pressure, 
soil heat flux data sets were plotted and reviewed by the data analyst for consistency and 
accuracy by comparing results with other measurements for the duration of each test plus one 
hour before and after each test.

There are two files that provide the non-sonic anemometer data (10 min and 30 min). The 
filenames are ‘RM_##min.csv’ where ‘##’ specifies the averaging period (10 or 30 min). Missing 
values are indicated by ‘-999’. The column headers are:
