title: Processed and quality controlled surface fluxes and meteorological observations at Westham Island (CA-Wes)

description: Eddy covariance fluxes and meteorological observations at Westham Island (CA-Wes), an eddy covariance tower operated by the University of British Columbia (UBC) Vacouver, over unmanaged grassland site in the Lower Fraser Valley on in the Delta of the Fraser (Delta, BC, Canada) between 2007 and 2009. The site was operated as a rural reference site during the EPiCC project for evaluating models and contrasting urban observations.

The flux data processing is described here: https://dx.doi.org/10.14288/1.0103593

Files containing fluxes are organized in monthly comma-separated text files using the naming convention "Westham-Island-EC-XXXX-YY", where XXXX is the year and YY is the month of the year. All flux data has a 30-min time resolution and contains the following fields:
