Description
This product is a result of the use of a decision tree-based advanced machine learning algorithm (XGB) combined with an ensemble approach to predict the surface total alkalinity (TA) of the North Indian Ocean (NIO) (Longitude: 50E-100E, Latitude: 0-26N) using ship-based observations collected from different sources for the period 1978-2019 and a reanalysis data product. The ensemble approach enables the development of the best high-resolution (1/12°) surface TA estimates (INCOIS_TA) with an uncertainty map. This data has a monthly frequency and ranges from 1993 to 2020.
