Description: DAC-ERA5 is based on a TUGO simulation forced by ERA5 meteorological reanalysis. DAC-ERA5 product is a combination between TUGO HR barotropic model output (high frequencies) and the Inverted Barometer correction (IB, low frequencies). The cutoff period used to separate high and low frequencies is 20 days.
