GNSS troposphere products from a network of low-cost GNSS receivers, Wroclaw, Poland, March-April 2021

This dataset contains multi-GNSS troposphere products, i.e. ECEF coordinates, zenith total delay (ZTD), and horizontal gradients, together with their uncertainties. These products were obtained using 3 processing strategies:

1) real-time (for details see https://link.springer.com/article/10.1007/s10291-020-01014-w, under to "advanced strategy" configuration, with the exception that only GPS and Galileo observations were considered);

2) near real-time (NRT, for details see http://egvap.dmi.dk/);

3) final (using CSRS online service, https://webapp.geod.nrcan.gc.ca/geod/tools-outils/ppp.php).

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

For convenience, the same information is stored in alternative data formats:

1) for NRT and Final products: troposphere SINEX v1 (TRO / TRP)

2) for real-time products: semicolon-delimited text files, with a self-explanatory header line; each file contains daily products for one station.
