Perdigao: ISFS High-rate Surface Meteorology and Flux Products

Summary

This dataset contains quality controlled, high-rate surface flux data collected by the Integrated Surface Flux System (ISFS) during the Perdigao field campaign. These data are in NetCDF format and the sonic winds have been corrected for boom orientation and tilt, and are thus rotated into a geographic coordinate system. The quality control proceedures and corrections applied to the data, as well as any uncorrectable issues are described in detail in the accompanying Data QC Report document. These data have been bundled into daily TAR archives and compressed using gzip. Each day of data is approximately 8 GB uncompressed.
