5 Minute Statistics of ISFF data during CASES-99

Summary

These data contain surface meteorology measurements of the Integrated Surface Flux Facility (ISFF) during the CASES99 field project, in October, 1999. Note: ISFF is now know as ISFS.

The 5 minute files contain means, variances and covariances of ISFF variables that were sampled on the main tower and the six outlying towers. We recommend combining these to obtain more statistically-significant averages over longer time periods.

These data have not been quality-controlled. Sonic winds have been rotated to geographic coordinates and tilt corrected. The data are stored in NetCDF files. Information on the NetCDF file format and software is available at http://www.unidata.ucar.edu/software/netcdf/. Information specfic to ISFS NetCDF files is available at https://www.eol.ucar.edu/content/isfs-netcdf-files.

The NetCDF file names are cases.99MMDD.nc, where MMDD is the starting month and day in UTC.
