GCIP/ESOP-98 Rosemount, MN Flux Data Set

1.0  General Information


     This data set was provided to UCAR/JOSS by Dr. John Baker Soil Scientist
     at the USDA/ARS and an Adjunct Associate Professor at the Department of
     Soil, Water, and Climate at the University of Minnesota.  For further
     information on these data please contact him via e-mail
     (jbaker@soils.umn.edu) or phone at (612) 625-4249.


2.0  Quality Control Information


     These data were quality assured and quality controlled at the University
     of Minnesota, UCAR/JOSS has not changed these data in any way, and has 
     conducted no quality control on this data set.

     Periods of missing data are primarily due to precipitation.


3.0  Site Location


     The Rosemount field site is located at:

              Latitude           Longitude           Elevation (msl)
            -----------         -----------         -----------------
  
          44 42' 51.50" N      93 5' 23.66" W            293.57 m


4.0  Instrumentation


     The data were collected using a Campbell Scientific CSAT3 3-D sonic 
     anemometer and a krypton hygrometer.  Coordinate rotations have been 
     performed.


5.0  Data Set Information


     Field data measured at Rosemount, MN for the period 2 October 1997
     (Julian day 275) to 31 May 1998 (Julian day 151) can be found in the
     following comma delineated files:

FLUXES.CSV

This file contains fluxes computed from eddy covariance data for Rosemount, MN 
for the winter of 1997-1998.  The data were collected using a Campbell Scientific 
CSAT3 3-D sonic anemometer and a krypton hygrometer.  Coordinate rotations have 
been performed.  The file is in comma-delineated ASCII format and has five columns:

Column 1: time, in decimal days; i.e. 6:00 AM on December 31, 1997 is expressed 
          as 365.25.

Column 2: latent heat flux, in W m-2.

Column 3: virtual sensible heat flux, in W m-2.  This was computed from the 
          covariance of vertical windspeed and temperature computed from the 
          speed of sound.

Column 4: sensible heat flux, in W m-2. This was computed from covariance of 
          vertical windspeed and temperature of a fine-wire thermocouple. There 
          is only a limited amount of these data.

Column 5: Shear stress, in m2s-2.
