Meteorology, Vegetation, Radiation, Microtopography, and Thaw Depth Data, 
Alaska, 1995-1996

Data include temperature, relative humidity, long- and short-wave radiation, 
photosynthetically active radiation (PAR), leaf area index (LAI), 
microtopography, and thaw depth data for study sites on the North Slope of 
Alaska. Meteorological parameters were measured at 20-second intervals and 
averaged to 6-minute records in a data logger. Data were later averaged to one 
hour. Radiation data were recorded every hour. Microtopography and thaw depths 
were measured by Terry Chapin's group from the University of California at 
Berkeley.  Resolution of height contours is 0.3048 cm (1/100 of a foot).  Thaw 
depths are given in meters. 

It was found that several of the original documentation files were redundant
or incorrectly located and/or named, and these were deleted, moved, or
renamed as appropriate on April 10, 2002. The tar files were then rebuilt, 
and this file (arcss012doc.txt) was created on that date as well.

The 1995 data are combined in the 1995.tar file, which contains the
following:
