Dynamic Atmospheric Correction product using ERA5

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.

The product is delivered with one hour time-step on a 1/8° regular grid.
