s2ard

A python project which will convert a Sentinel2 Level 2A image into a JRSRP Surface Reflectance product with BRDF correction. This forms one of the JRSRP's analysis ready data (ARD) sets. The approach uses code from jrsrp-sen2brdf. See Flood, N. (2020). Assessing BRDF effects in the Sentinel-2 Level 2A product in the Australian landscape. Joint Remote Sensing Research Program. for details.

Installation

Since the code depends on a jrsrp-sen2brdf which is not available on pypi, users need to manually install along with this package, eg

uv add jrsrp-s2ard "git+https://gitlab.com/jrsrp/sys/sentinel2/jrsrp-sen2brdf@v1.0.2"

Usage

Input is typically via a STAC item collection. An example is:

curl \
    https://earth-search.aws.element84.com/v1/collections/sentinel-2-c1-l2a/items/S2B_T53KLA_20250711T012135_L2A \
    -o eg.json
uv run stac2ard -c eg.json -b B04 -b B03 -b B02

This will produce the output files cfmsre_t53kla_20250711_bbam3_B04.tif, cfmsre_t53kla_20250711_bbam3_B03.tif, cfmsre_t53kla_20250711_bbam3_B02.tif.
