   The available data product has been processed to a Level 1 standard. This 
   means that raw data (Level 0 data), which were downloaded on approximately a 
   6-month basis, have been concatenated into one continuous file per 
   meteorological tower. Data have then been filtered twice for faulty values. 
   The first filtering process was done manually to recognize instrument, wiring, 
   or programming problems. The second filtering process was done computationally 
   to remove blank values or any faulty values that fall outside of acceptable 
   boundaries for each instrument (see table below for instrument list). Faulty 
   data and missing data were replaced with a default value of 8999.

Group: Summary

   This data set contains meteorological observations at 36 sites throughout the 
   Small Regional Study Area (SRSA) of the NASA Cold Land Processes Field 
   Experiment (CLPX) in Colorado, USA. Identical meteorological towers were 
   located close to the four corners of nine 1 km x 1 km Intensive Study Areas 
   (ISAs). At each site, measurements of air temperature, relative humidity, wind 
   speed, and wind direction were made at 2 m (North Park) or 4 m (Frasier and 
   Buffalo Pass) above ground level. Snow depth, soil moisture, and soil 
   temperatures were also measured. Hourly meteorological observations were 
   recorded between 20 September 2002 and 1 October 2003, although data were not 
   necessarily continuous throughout this time period for all towers.

   The NASA CLPX is a multi-sensor, multi-scale experiment that focuses on 
   extending a local-scale understanding of water fluxes, storage, and 
   transformations to regional and global scales. Within a framework of nested 
   study areas in the central Rocky Mountains of the western United States, 
   ranging from 1-ha to 160,000 km^2, intensive ground, airborne, and spaceborne 
   observations are collected. Data collection focuses on two seasons: 
   mid-winter, when conditions are generally frozen and dry; and early spring, a 
   transitional period when both frozen and thawed, dry and wet conditions are 
   widespread.
