Data for: Patterns of ecosystem-level adaptation in tidal wetlands

We only used the purest and most reliable data in our final analysis. We filtered 782,693 tidal wetland pixel locations with coverage spanning the entire contiguous United States to only include those with greater than 90% tidal wetland class purity. We then further filtered these pixels to only include those where data dropouts in the EVI or QA layer occur fewer than 10% of the time. In the end, we used 145,871 pixels in our analysis. The file named "MOD13GPPalgorithm_FINAL.R" contains scripts that filter the EVI, short wave radiation (SWR), and air temperature input databases and then calculate gross primary productivity (GPP) using these input files. Tidal wetland GPP was calculated for the dates 3/5/2000 to 12/2/2020 at 16-day intervals using the algorithm published in:

The file named "SWR_90percentFinal.csv" contains the filtered SWR database used to calculate GPP. File named "temp_90percentFinal_rounded.csv" contains the filtered air temperature database used to calculate GPP. The file named "EVI(gapped_filled)_90percentFinal.csv" contains the final gap-filled EVI time series database used to calculate GPP. File named "QA_90%Final.csv" contains the filtered quality assurance (QA) values. Dates in the EVI database where QA = 3 were determined to be of poor quality, removed from the database, and replaced with "NA". Single NA gaps in the EVI database were gap-filled by taking the mean of the dates flanking the NA gap. File named "myGPP(gap_filled)_FINAL.csv" contains the calculated GPP estimates used throughout the study analysis. 
File named "rawEVI.csv" contains the raw EVI database prior to filtering and gap-filling. File named "rawSWR.csv" contains the raw SWR database prior to filtering. File named "rawAirTemp.csv" contains the air temperature database prior to filtering. File named "rawQA.csv" contains the QA layer of the MOD13 satellite product prior to filtering. These files contain the raw data for all 782,693 tidal wetland pixel locations. These raw files can also be accessed at daac.ornl.gov.
