Estimation of Land Surface Temperature under Cloudy Skies Using Combined Diurnal Solar Radiation and Surface Temperature Evolution

Abstract: Land surface temperature (LST) is a key parameter in the interaction of the land-atmosphere system. However, clouds affect the retrieval of LST data from thermal-infrared remote sensing data. Thus, it is important to determine a method for estimating LSTs at times when the sky is overcast. Based on a one-dimensional heat transfer equation and on the evolution of daily temperatures and net shortwave solar radiation (NSSR), a new method for estimating LSTs under cloudy skies (Tcloud) from diurnal NSSR and surfac… Show more

“…Traditionally, the applicability of land surface models is limited due to complex model parameterization and the limited availability of "ground truth" or in situ data for parameter calibration. As shown in this study, one solution for this limitation is using remote-sensing-based observations or estimates as "ground truth" for model calibration (Stisen et al, 2011;Zhang et al, 2009). This study calibrated the model parameters through remote sensing snapshot (UAS) estimates of land surface variables such as T s and θ and provided an example of integrating remote sensing data and process-based models.…”

“…Once the parameters are determined, surface temperature at any time of a day is able to be predicted. Besides, DTC models are helpful for atmospheric corrections on satellite observations (Jiang et al., 2006; Schädlich et al., 2001), temporal normalization of remotely sensed LSTs (Jiang, 2007), estimation of LST under cloudy condition (Liu et al., 2017; Zhang et al., 2015), estimation of surface air temperature (Gholamnia et al., 2017), and improvement of cloud‐screening algorithms (Inamdar et al., 2008). They are also promising to be used in simultaneously retrieving LST and Land Surface Emissivity (LSE) from multi‐spectral and multi‐temporal observations of geostationary satellites (Li, Tang et al., 2013).…”

“…Lu, et al [19] improved the neighboring pixel method by introducing satellite observations. Zhang, et al [20] used a one-dimensional heat transfer model to reconstruct cloudy pixels. In statistical methods, the solution for recovering cloudy MODIS LST pixels is to introduce microwave temperature brightness (TB) data due to penetrating clouds.…”
