The daily measured AET data collected at the ET stations were used to calculate the monthly totals for each month of the year. These monthly AET totals were then used to calculate the average AET/RET monthly ratios for the land cover of the ET station by dividing the AET rates by the RET rates obtained from the Florida ET network (http://fl.water.usgs.gov/et/; USGS, 2016). The land cover types represented in these data are forest, grass, marsh, open water, ridge, urban, and agriculture. The AET/RET ratios for these land cover types were presented...
