ESA Water Vapour Climate Change Initiative (Water_Vapour_cci): Total Column Water Vapour daily gridded data over land at 0.5 degree resolution, version 4.2 2004-11

This dataset consists of daily total column water vapour (TCWV) over land, at a 0.5 degree resolution, observed by various satellite instruments. It has been produced by the European Space Agency Water Vapour Climate Change Initiative (Water_Vapour_cci), and forms part of their TCVW over land Climate Data Record 1 (TCWV-land (CDR-1)).This version of the data is v4.2. This is an updated dataset from the v3.2 product, in summary providing the following improvements:- Time series has been extended, now covering years 2000-2023.- L1b input data has been extended by using the full time range of Terra MODIS measurements, and by ingesting Aqua MODIS and Sentinel-3 OLCI-B as additional sensors.- Number of L2 observations contributing to a L3 grid cell is now provided per single sensor.- Flags have been revised and extended.
