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.… See the full description on the dataset page: https://huggingface.co/datasets/asterisk-labs/clouds-decoded-rain-check.

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.

Layers

Each scene directory holds these per-scene PNGs:

File	Description
`true_colour.png`	RGB true-colour composite
`cloud_mask.png`	cloud / clear mask
`cloud_height.png`	cloud-top height (m)
`ice_composite.png`	ice / phase composite
`properties_tau.png`	cloud optical thickness (τ)
`properties_r_eff_liq.png`	liquid effective radius (µm)
`properties_r_eff_ice.png`	ice effective radius (µm)
`properties_ice_liq_ratio.png`	ice / liquid ratio (thermodynamic phase)
`properties_uncertainty.png`	retrieval uncertainty
`overview.png`	combined multi-panel overview

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.
