Met data from Chemistry Tower
John Ortega, NCAR, Atmospheric Chemistry Observations and Modeling

Meteorological data was taken at 1 Hz from 4 levels on the chemistry tower:  1.8m (level 1), 7.0m, 14.1m, and 27.8m (level 4).  Data archived here is avergaged every 5 minutes.  The data file for each day should have exactly 288 lines -1 line for
each 5 minute period.  The columns in the text files are the following:
1.  Time (Matlab day)  January 1, 2016 = 736330
2.  Time (decimial day of year; July 7 = 189 in 2016 (188 for non leap years).
3.  Temperature in deg C
4.  % Relative humidity
5.  Pressure in mb (1 mb = 1 hPa)
6.  Wind speed in m/s
7.  Wind direction in degrees (north = 0, west = 270, etc.).

Wind directions were broken down into their sine and cosine components prior to averaging.

Missing data is listed at -8888.

The met data on level 4 is oriented 30 degrees east of north, so the wind direction data has 30 degrees subtracted from it in the final data.  This has been taken into account in all of the data files, but not in the plots (jpeg files: "WS_2016XXXX.jpg" where XXXX is the day and month (e.g. 0809 = August 9 or 1030 = October 30).

Wind speed for all 4 levels:  "WS_2016XXXX.jpg"
Wind direction for all 4 levels:  "WD_2016XXXX.jpg"
Temperature for all for levels:  "Temp_2016XXXX.jpg"
Relative humidity for all 4 levels:  "RH_2016XXXX.jpg"

The following data files are available in tab-delimited text:
5 minute data for single day:  "MET_levelX_2016YYYY.txt where X is the level 1-4 and YYYY is the month and day as described above.
5 minute data for the July 7-August 20:   "MET_levelX_July7_Aug20.txt" wher X is the level 1-4.

The time stamp in columns 1 and 2 are the middle (2:30) of each 5 minute period.  Time is
