    SMOS near real time products include Level 1 geo-located brightness temperature and Level 2 geo-located soil moisture estimation.

    The SMOS Near Real Time (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 Near Neal Time (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.
