Sentinel 2 data: satellite and sun zenith angles

[lbertoncini]

Dear all,

I am currently working on MSI Sentinel 2 products. To conduct my study I would need to retrieve satellite and sun zenith angles for each S2 product. Actually, I don’t know where I could find these last, even in the metadata file. If you have any idea it would be helpful !

Thanks all,

Lucas.

have you checked these?

@lbertoncini

Values for Sun Zenith and Azimuth Angle (including the Mean for both) and Viewing Incidence Angles can be found in the L1C Tile metadata (MTD_TL.xml).

Thank you very much !

Really helpful, I appreciate

Note that you can use the S2 resampler module to compute proper viewing geometrie parameters for every single pixel.

but it may be quite heavy in memory usage:

Large time difference when using core or s2tbx resamplers for S2 data (with view angles) from

Hello, As a follow-up to this topic Generate view angles from metadata Sentinel-2 I tried both the core (generic) and the s2tbx resampling operators. The s2tbx enables one to get accurate values for the viewing angles of S2-msi pixels. But, the s2tbx (‘org.esa.s2tbx.s2msi.resampler.S2ResamplingOp’) is very slow when called from snappy, and rapidly saturates memory (memory use keeps increasing when loading a second time the same data, hereafter “2nd call”). Attached is a small code to test th…
