Multitemporal Seasonal Tabular Data Products Derived from Landsat Imagery for the Selected Ciénegas and Surrounding Floodplains of the Greater Madrean Archipelago Ecoregion, 1985-2023

Ciénegas are wetlands in arid and semi-arid regions of North America. We quantified changes in ciénega condition and floodplain dynamics using the detailed boundaries of 31 ciénegas and their respective controls.This data release is a series of four data collections consisting of 68 tabular data files (.csv) that include the following:
(i) “i_Cienega_Timeseries_CSVs.zip” data collection consisting of 31 tabular data files (i.e., one for each ciénega) displaying yearly January to June precipitation and 31 tabular data files (i.e., one for each ciénega) displaying a seasonal time series of NDVI, NDII, and precipitation;
(ii) “ii_Cienega_Slope_CSVs.zip” data collection consisting of 1 tabular data file displaying seasonal Sen’s slope results and corresponding p-values for NDVI, NDII, and precipitation for each ciénega, and it’s respective control, on a seasonal time scale;
(iii) “iii_Histogram”CSVs.zip” data collection consisting of 4 tabular data files displaying Sen’s slope and corresponding p-values of high greenness conditions for each ciénega, yearly time series of high greenness conditions for each ciénega, seasonal histogram statistics for each ciénega, and the NDVI and NDII scores for 2023; and
(iv) “iv_Staitstical_Variable_Assessment.zip” data collection consisting of 1 tabular data file containing data variables for each ciénega.
