Interactive comment on “ Multi-approach gravity field models from Swarm GPS data ” by João

The authors combine several instrument data sets and analysis methods to provide a series of gravity fields for the Swarm mission. Results of a multi-analysis combination solution are compared to individual ones and to GRACE results. The paper provides several methodological analyses, new approaches explored, and it describes intermediate data sets such as kinematic orbits and the accelerometry/non-conservative force modelling. The authors, apparently, also have set up standardized and officialized workflows which is encouraging.
