Reports from R. Eresmaa et al highlight recent research in meteorology

"Numerical weather prediction (NWP) model output can be used for derivation of tropospheric delay correction in order to decrease positioning errors of Global Navigation Satellite System (GNSS) applications. In precise geodetic positioning it is possible to make use of corrections that are derived separately for all GNSS signal paths," scientists in Helsinki, Finland report. "Due to the large amounts of data, this approach is considered impractical froth real-tithe mobile positioning point of view. This article introduces several parameterization schemes that provide a zenith- and azimuth-angle-dependent description of tropospheric delay correction at a single observation...
