Real-time ZTD and gradients from 20 IGS stations; year 2019

This dataset contains multi-GNSS real-time products, i.e. ECEF coordinates, zenith total delay (ZTD), and horizontal gradients, together with their uncertainties estimated every 1 minute over the entire year 2019 for 20 IGS stations: ALGO, BIK0, CAS1, CHPG, CPVG, FAA1, JPLM, KERG, KZN2, LHAZZ, LMMF, NKLG, NNOR, PNGM, POVE, REYK, RGDG, ULAD, WROC, YEL2.

Two subsets are available that correspond to two processing strategies, i.e. common and advanced. A detailed description, validation and comparison of both strategies can be found in: https://link.springer.com/article/10.1007/s10291-020-01014-w

Data are stored in standard Matlab MAT files. Each file contains a single table array (Matlab format) with the complete set of estimated parameters for a single station. Table columns are labeled and self-explanatory. A comma-delimited text file can be obtained using in-build Matlab function "writetable.m".
