Sentinel-2 Cloud Property Retrievals over the UK and India
Rendered per-scene quicklook layers of cloud optical and microphysical properties retrieved from Sentinel-2 (MSI) Level-1C imagery over eight tiles (four in the UK and four in India). These images power the interactive report at asterisk-labs-clouds-decoded-rain-check.static.hf.space. Cloud properties are estimated with the clouds-decoded retrieval code, developed as part of the clouds decoded project funded by ARIA.
Coverage
| Region | Tiles (MGRS) |
|---|---|
| UK | T29VMC, T30UVA, T31UDA, T31VDF |
| India | T42QYE, T43PDM, T44PNB, T45QWB |
~8,400 scenes spanning 2015–2026; each tile is ~110 × 110 km.

Layout
figures/<SCENE_ID>/<layer>.png
<SCENE_ID> is the Sentinel-2 L1C product identifier
(e.g. S2A_MSIL1C_20150712T111036_N0500_R137_T31UDA_20231010T005751), which
encodes the acquisition date, relative orbit and MGRS tile.
