Short Wave upwelling Radiative Flux (SWupRF) by Argus 1000 micro-spectrometer - A new study for Earth energy balance.

This new study develops an algorithm for Short Wave upwelling Radiative Flux (SWupRF) for the spectral variations within 1100 to 1700 NIR wavelength band based on remote sensing date set of Argus 1000 micro-spectrometer observations. We calculate the SWupRF by investigating the total radiative flux due to O2, H2O, CO2 and CH4 and also by the individual gas within the selected wavelength bands of interest. A GENSPECT synthetic line by line radiative transfer model is applied to perform radiative transfer simulations to calculate the radiative flux by varying surface albedo, mixing ratios of the selected greenhouse gases, surface temperature, solar sun and zenith angles with different latitude and longitude of the instrument. Finally, the SWupRFsyn estimated from GENSPECT was compared with SWupRFobs from Argus 1000 over a period of four years (2009 and 2013) covering all seasons. Thus, this study shows the remote sensing of SWupRF within a small wavelength band can be a better foundation for future source for estimating the energy balance as well as for the efficient detection of cloud scene.
