WebMCD18A1 does not directly provide the daily DSR value. However, the eight 3-h MCD18A1 DSR values during a day can be conveniently averaged to obtain daily mean DSR. While it is a simple approach, such an averaging method fails to account for nonlinearity in DSR time series data and can introduce some levels of uncertainties in estimating daily DSR. Web15 dec. 2024 · MCD18A1 and ISCCP-HXG-SSR products only have SWDR component, and the (r)RMSE is greater than (40%)100 W/m 2 in the polar regions. The accuracy of ISCCP-HXG-SSR product in the Arctic is better than that of MCD18A1 product, but the quality of product in the Qinghai-Tibet Plateau is worse than that of MCD18A1. how to order covid tests free

Web16 feb. 2024 · General Accuracy Statement. MODIS downward shortwave radiation (DSR) and photosynthetically active radiation (PAR) products (MCD18) are currently considered to be Validated Stage 1. The MCD18 data products were assessed with field measurements of DSR and PAR collected at BSRN, AmeriFlux, European Flux and OzFlux stations across … WebThis means that we are talking about instantaneous power measurement. As a reminder, 1W = 1J/s. You can calculate the total energy of PAR in one day within an area of 1 m 2 simply averaging the ...
