blue arrow DESCRIPTION

SMOS Near Real Time products include Level 1 geo-located brightness temperature and Level 2 geo-located soil moisture estimation.  For an optimal exploitation of the SMOS NRT products please consult the read-me-first notes.

The SMOS NRT Light BUFR product contains brightness temperature geo-located on Gaussian grid (T511/N256 only for land pixels but keeping full angular resolution. The pixels are consolidated in a full orbit dump segment (100 minutes of sensing time) with a maximum size of about 30MB per orbit. Spatial resolution is in the range of 30-50 km. This product is distributed in BUFR format.

The SMOS NRT L2 Soil Moisture Neural Network (NN) product provides a near real time soil moisture dataset based on the statistical coefficients estimated by a neural network. It is provided in the SMOS DGG grid and only at the satellite track. It also provides an estimation of the uncertainty of the estimated soil moisture product and the probability that a soil moisture value is contaminated by Radio Frequency Interference. This product is distributed in NetCDF format.

The SMOS NRT data products are also distributed via the EUMETCast Europe Service (DVB), upon registration on the EUMETSAT Earth Observation Portal (the Ku-band DVB reception station must be situated within the service coverage in Europe). They are regularly delivered to the UK Met-Office and made available to operational agencies and research and development institutes via the WMO GTS Network.For an optimal exploitation of the SMOS NRT products please consult the read-me-first notes. available in the Resources section below.
