X-TRACK Dynamic Atmospheric Correction (DAC)

The X-TRACK DAC is computed as the combination of high-frequency elevations from the global Mog2D/T-UGOm 2D model (Carrere and Lyard 2003, see References) simulations plus low-frequency elevations from inverted barometer law (using ECMWF atmospheric pressure products).

X-TRACK DAC corrections are delivered also in a separate field in case users would want to use another tidal correction.
