In this study, two collection 6 (C6) Moderate Resolution Imaging Spectroradiometer (MODIS) level-2 land surface temperature (LST) products (MYD11_L2 and MYD21_L2) from the Aqua satellite were evaluated using temperature-based (T-based) radiance-based (R-based) validation methods over barren surfaces in Northwestern China. The ground measurements collected at four sites June 2012 to September 2018 during Heihe Watershed Allied Telemetry Experimental Research (HiWATER) experiment used perform...
Land surface temperature (LST) is a vital parameter for studying global ecological, climatic, and environmental changes. Although various LST retrieval algorithms have been proposed, including split-window (SW), dual-window (DW), three-channel (TC), dual-angle (DA) algorithms, few studies compared these using the same satellite observations. The Sea Surface Temperature Radiometer (SLSTR) onboard Sentinel-3A provides unique opportunity to conduct this comparison owing its viewing capability...
In this study, to improve the accuracy of land surface temperature (LST) products over barren surfaces, we present an operational algorithm retrieve LST from Moderate-Resolution Imaging Spectroradiometer (MODIS) thermal infrared data using physically retrieved emissivity products. The involved two steps. First, in MODIS split-window (SW) channels was estimated vegetation cover method, with bare soil component derived ASTER global set. Then, a modified generalized SW algorithm. This...
Radiometric measurements in the Thermal Infrared (TIR) domain exhibit an angular variation over most surface types, known as Radiation Directionality (TRD) phenomenon. A primary objective of ongoing development TRD physical models is to perform a correction effects obtain comparable land temperature products. In practice, it advised handle only having limited number input parameters for purpose operational applications. The use semi-empirical kernel-driven (KDMs) appears be good tradeoff...
Land surface temperature (LST) is an important parameter that characterizes the energy balance of land surface, and it widely used in various research fields. This paper proposes operational split-window (SW) algorithm for use with Chinese Fengyun-3 (FY-3) series satellite data, purpose generating long-term global LST products. The primarily involves three steps. First, brightness temperatures FY-3 Visible Infra-Red Radiometer (VIRR) were recalibrated using historical recalibration...
A new directional canopy emissivity model (CE-P) based on spectral invariants is proposed in this paper. First, we prove the existence of invariant properties thermal infrared (TIR) band using a Monte Carlo model. Based it, equation derived from perspective absorption. In expression, single-scattering and multiscattering effects are separated analytically TIR band. We find that overall contribution multiple scatterings less than 0.005 when component emissivities over 0.90, decreases with...
Land surface component temperatures are important inputs in longwave radiation and evapotranspiration estimation models. Most temperature inversion approaches focus only on two components, namely, soil leaves, because space-based multiangle observations lacking. This approach is inconsistent with ground-based measurements, which suggest that the of sunlit shaded may significantly differ. paper explores a three-component scheme uses airborne thermal infrared to decrease difference between...
Surface upward longwave radiation (SULR) is an important component of the surface energy balance and closely related to land temperature emissivity. The estimation SULR plays role in study circulation climate change. State-of-the-art methods estimate SULR, including physical method hybrid method, are conducted without considering directional thermal (DTR), which may induce a large error estimation, particularly over sparsely vegetated surfaces. In this paper, we modified...
Surface upward longwave radiation (SULR) is a significant component of the surface budget and closely linked with evapotranspiration, soil moisture, cooling on clear nights. Therefore, accurately estimating SULR essential to better understand its spatiotemporal dynamics or characterize thermal environment given land surface. Currently, most methods for (including physical hybrid methods) fail account anisotropy, which can introduce errors into calculation. We previously proposed combined...
Many physical models have been proposed to simulate the directional anisotropy in thermal infrared (TIR) region over vegetation canopies produce angular corrected brightness temperature or land surface temperature. However, too many input parameters obstruct their operational use. Semiempirical kernel-driven are designed be a tradeoff between accuracy and operationality. Recently, four proposed: first two direct extensions of kernel visible- near-infrared last were directly for TIR region....
Surface upward longwave radiation (SULR) is one of the four components surface net radiation. Geostationary satellites can provide high temporal but coarse spatial resolution SULR products. Downscaling to a higher important for fine-scale thermal condition monitoring. Statistical regression downscaling widely used due its simplicity and built on assumption that parameter like land temperature (LST) or has relationship with related factors normalized difference vegetation index (NDVI),...
