Abstract

GRACE/GRACE-FO Level-3 product based on COST-G RL02 Level-2B products (Dahle & Murböck, 2025) representing Ocean Bottom Pressure (OBP) variations provided at 1° latitude-longitude grids as defined over ocean areas. The OBP grids are provided in NetCDF format containing seven different variables:

1) 'barslv': gravity-based barystatic sea-level pressure
2) 'std_barslv': gravity-based barystatic sea-level pressure standard deviations
3) 'resobp': gravity-based residual ocean circulation bottom pressure
4) 'std_resobp': gravity-based residual ocean circulation bottom pressure standard deviations
5) 'leakage': apparent gravity-based bottom pressure due to continental leakage contained in 'resobp'
6) 'model_ocean': background-model ocean circulation pressure
7) 'model_atmosphere': background-model atmospheric surface pressure

These Level-3 products are visualized at GFZ's web portal GravIS (https://gravis.gfz.de).
