CORAL-TT (Calculating Oscillations in Regional Aquatic Locations - Temperature and Turbidity)(LAR-19547-1)

The JavaScript code intended for Google Earth Engine (GEE) allows easy access to all data available on this free platform, calculates Normalized Difference Turbidity Index (NDTI) median over years and seasons, and calculates fluctuations between seasons. The code combines Surface Reflectance Tier 1 data from Landsat 5 Thematic Mapper (TM), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), and Landsat 8 Operational Land Imager (OLI) data from 1991 to 2018, and Level 2 Sentinel-2 Multispectral Instrument (MSI) data from 2015 to 2018. Furthermore, the software maps SST using Level 3 Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) processed by Earth Observing System Data and Information System (EOSDIS). The GEE user interface presents a graph that allows users to see fluctuations in SST at any given selected point of interest over time. The user can also specify dates, image collections, and a study area to display and export a map of interest.
