| Summary: | Introduction Implementation at Takuvik of the algorithm of (Belanger, Babin et al. 2013) to compute daily primary productivities and other physical and biological products above 45° North. Data and Methods Data The primary production model used three kinds of data. The three kinds of data were sea ice concentrations, atmospheric products and water-leaving reflectances (Rrs). Two data sets were used for the sea ice concentrations. The title of the first data set is Sea Ice Concentrations from Nimbus-7 Scanning Multichannel Microwave Radiometer (SMMR) and Defense Meteorological Satellite Program (DMSP) Special Sensor Microwave Imager (SSM/I)-Special Sensor Microwave Imager/Sounder (SSMIS) Passive Microwave Data (Cavalieri 1996, updated yearly) (v1.1). This data set comes from the National Snow and Ice Data Center (NSIDC) (ftp://sidads.colorado.edu/pub/DATASETS/nsidc0051_gsfc_nasateam_seaice). This data set was used for years 1998 through 2015. From 1998 to 2007, the platform DMSP-F13 and the instrument SSM/I were used. From 2008 to 2015, the platform DMSP-F17 and the instrument SSMIS were used. The temporal resolution is daily. The spatial resolution is 25 x 25 km. The title of the second sea ice concentration data set is Near-Real-Time DMSP SSM/I-SSMIS Daily Polar Gridded Sea Ice Concentrations (Maslanik 1999, updated daily). This data set comes from the NSIDC (ftp://sidads.colorado.edu/pub/DATASETS/nsidc0081_nrt_nasateam_seaice/). This data set was used for year 2016. The platform DMSP-F17 and the instrument SSMIS were used. The temporal resolution is daily. The spatial resolution is 25 x 25 km. The atmospheric products data were the total ozone concentration O3, cloud fraction CF over the pixel and cloud optical thickness τCL. Two data sets were used and compared. The title of the first data set is Flux Data-Surface Radiative Fluxes (FD-SRF). The product total column ozone (tlo3__) was used for the parameter O3. The product mean cloud fraction (cf_m__) was used for the parameter CF. The product Mean cloud ... |
