Perdigao: ISFS 5-minute Surface Meteorology and Flux Products

Summary

This dataset contains quality controlled, 5-minute 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.

Identifier	DOI: https://doi.org/10.26023/ZDMJ-D1TY-FG14
Data Quality	final
Versions	0.1 (2017-06-26) 0.2 (2017-10-26): Corrections have been applied to the sonic wind directions in order to rotate them into correct geographic coordinates. This dataset is also more complete. 1.0 (2018-12-12) 1.1 (2019-02-15): This version includes QC'd data from the ARL towers, which consists of towers 12-16 along transect northwest, as well as an additional correction to Qoil measurments. 1.2 (2021-07-12): These files should be identical to those in v1.1, but with position variables (latitude, longitude, altitude) updated to include all towers and with values from the DTU Leica multistation scans. (Only the current version of the data is available to order. If you have questions about a prior version, please email us.)
