GNSS antennas (Integrated Water Vapour)

GNSS antennas are operated on both sites CRA and PDM by the Observatoire Midi-Pyrénées (OMP) / Géosciences Environnement Toulouse Laboratory (GET). The two antennas are part of two French permanent GNSS networks, RENAG (CNRS INSU) and RGP (IGN).

In the context of ACTRIS-France, integrated water-vapor atmospheric columns are provided as side-products of position measurements. Data are available from the AERIS catalogue.
