1.0  General Description

This dataset contains supplemental data from NCAR's Meteorological Stations. 
Data includes pressure, temperature, humidity, wind speed and wind
direction for the IHOP_2002 time period.  Five stations are represented
in this dataset.  Four of the stations' data is in ASCII comma delimited
format with a single file for each station for the entire time period.
The fifth station's data is in NetCDF format and is broken down into 
hourly files.


2.0  Data and Format Information

Four of the stations are in the format described below, the fifth is
in NetCDF format.  

This data is represented in the following comma delimited format.

Station ID,Pressure(mb),Temp(C),Humidity(%),Windspeed(M/S),Winddirection(degrees),Julian Day,HHMM

Station ID should be ignored, as it reports 108 for all stations.

The station ID was derived from the corresponding locations in the IHOP 
handout booklet.  Additional information regarding these stations is 
available from the IHOP booklet.

USER NOTES:

Ventilation fans failed on all stations during this project at sometime 
between May 18th(julian 138) and June 6th(julian 157) on the day they 
were replaced. There were no further failures from that date until 
the end of the project.(J 177)
Users should note that sensor arm heating may have occurred when 
windspeeds were low and daytime temperatures were high during this period.
