| attribute | NC_GLOBAL | summary | String | The unbiased relative difference (Psi) between primary productivity (netPP) calculated using VIIRS NOAA-20 data and MODIS Aqua data. For each pixel, psi is calculated as netPP(viirs)- netPP(modis) divided by the mean of netPP(viirs) and netPP(modis) as described by Mélina et al. 2017. Primary productivity was calculated as described by Behrenfeld and Falkowski 1997. The data are a 5-year mean from Jan 2018 to Dec 2022 and at 9km resolution. Input data for primary productivity were obtained from NASA and included chlorophyll_a, sea surface temperature, and photosynthetically active radiation from either MODIS Aqua or VIIRS NOAA20.. |
