Eddy Covariance observations of three different sites from Estero El Soldado, Sonora, Mexico

This database contains eddy covariance and micrometerogical measurements, it corresponds to three sites of study in Estero El Soldado (27.95413399, -110.9725342) Sonora, México. The flux tower was operating from June 12th 2018 to June 6st 2019. The dataset is divided in three sheets: site_1, site_2 and site_3 corresponding to the three sites where the tower was at each period. The three different  scenarios consider a) bare soil and seawater column (site_1) from June 12th to October 12th 2018,  n=134 days with 26 days of missing data, b) bare soil exposed some hours, seagrass present  and shallow seawater column (site_2) from October 13th 2018 to February 24th 201, n= 135 days with 54 days of missing data and, 3) seagrass present  and seawater column higher than previous case (site_3) from February 25th to June 6th 2019, with  n=102 days with 20 days of missing data.

A quality control filter was applied to the complete data set where outlier values were replaced with NaN. In addition to Mauder and Foken (2004) QC filter, we considered based on outliers the following cleaning : FCO2 values outside the range of -10 to 10 µmol m-2 s-1, as well as friction velocity (u*) >3 m s-1, shortwave incoming radiation >2000 W m-2, salinity <25 ppt and wind speed >25 m s-1.
