MONARCH-A deliverable D2.6.4: Gridded time series of GRACE-based freshwater pulses in the Arctic Ocean Authors: Valentina Barletta (vrba@space.dtu.dk) and Rene Forsberg (rf@space.dtu.dk), National Space Institute Technical University of Denmark, DTU Space, Juliane Maries Vej 30, DK-2100 Issue 0.1 Gridded GRACE solution over the Arctic Ocean using CSR release 05 and DDK3 filtering procedure. Grid file Results are a series of grid files containing global mass variations derived by GRACE+GAD (DTU_GRACE+GAD_solution_DDK3.zip). Files are indexed and the corresponding month for each index is indicated in the ASCII file list_time_csr.txt which has format: [index] [month index] [year] [first day of the months for GRACE data] [month of the year] Each grid has simple ASCII format: [longitude] [latitude] [value in mm of w.e] As additional product we provide the sequence of plot over the Arctic Ocean contained in the DTU_GRACE+GAD_ArticOc.pdf.
