ECOR VAP Flux Corrections, Gap-filling, and Results

An eddy correlation (ECOR) value-added product (VAP) has been developed that uses ECOR temperature, humidity, and wetness state (or default values of the same) to determine corrections to and gap-filling of the flux measurements. An outlier routine is used to remove obvious incorrect data before gap-filling is performed. For each month, diurnal half-hour averages of correct measurements are calculated and used to perform the gap-filling. Therefore, it is anticipated that the VAP would be run for each month of collected data. A data quality flag is included for each half-hour to indicate if any (and which) of the fluxes have been gap-filled (indicating an initial state of being incorrect or missing). Results of the VAP processing are shown and compared with the energy balance bowen ratio (EBBR) flux measurements for the Southern Great Plains (SGP) Central Facility.
