Sub-hourly Land Surface Temperature - Himawari/AHI, Split-window Algorithm with Solar Zenith Angle-based Calibration, Australia Coverage, 2015-2023
This geostationary land surface temperature (LST) collection was retrieved using Himawari/AHI observations and calibrated against MODerate-resolution Imaging Spectroradiometer (MODIS) best-quality retrievals for Australia. It was developed under an academic collaboration between the Australian National University (ANU) and the Commonwealth Scientific and Industrial Research Organisation (CSIRO). It has a spatial resolution of 2 km and temporal frequency of 10 min, and has been periodically updated since its inception in July 2015. This record has a temporal length of 8.5 years (i.e., Jul 2015 - Dec 2023) and the subsequent updates will be published annually.

- Purpose
- <p>The Himawari-8/9 satellites offer a unique opportunity to monitor sub-daily thermal dynamics over Asia and Oceania, and several operational LST retrieval algorithms have been developed for this purpose. However, studies have reported inconsistency between LST data obtained from geostationary and polar-orbiting platforms, particularly for daytime LST, which usually shows directional artifacts and can be strongly impacted by viewing and illumination geometries and shadowing effects. To overcome this challenge, we developed this collection, which utilised Solar Zenith Angle (SZA) as an ideal physical variable to quantify systematic differences between platforms. This LST collection demonstrated better consistency with LST obtained from both polar-orbiting platforms and ground-based measurements.</p>

- This LST collection was evaluated against Terra-, Aqua-MODIS and VIIRS LST, as well as in-situ LST from the <a href="https://www.ozflux.org.au/">OzFlux network</a>.
Report
Result
- Statement
- The median daytime bias (ubRMSE) of this collection against Terra-, Aqua-MODIS and VIIRS LST was 1.52 (2.75) K, 0.98 (2.44) K and -0.63 (2.94) K, respectively. In the evaluation against in-situ LST, the overall mean values of bias (ubRMSE) during daytime and nighttime were 1.41 (3.24) K and -0.06 (2.77) K based on 171,289 and 209,304 hourly samples, respectively, from 20 OzFlux sites across Australia between 01/Jan/2016 and 31/Dec/2020.
Resource lineage
- Statement
- <p>This LST collection was developed using a split-window algorithm, with its daytime component operationally adjusted using an SZA-based Calibration (SZAC) method. SZAC describes the spatial heterogeneity and magnitude of diurnal LST discrepancies from different products. The SZAC coefficient was spatiotemporally optimised against highest-quality assured (error <1 K) pixels from the MODIS daytime LST between 01/Jan/2016 and 31/Dec/2020.</p> See the method documentation for details.
