@@naureenfatima9715 Hi. Lmin is the spectral radiance scales to QCALMIN, while Lmax is the spectral radiance scales to QCALMAX. So accordingly you can calculate. For help, I am providing you the links to the websites that might help you. 1) yceo.yale.edu/how-convert-landsat-dns-top-atmosphere-toa-reflectance, 2) landsat.gsfc.nasa.gov/sites/landsat/files/2012/08/news_0077.pdf. You can easily calculate.
God job❤
radiance will calculate for only thermal band or for all bands?
you can calculate for all bands
the formula for the same is given in the USGS website
Are the values of TOA reflectance and radiance are same ?
How can I find radiance of sentinel 2 level 1C data ?
If you can tell me how to obtain these constants because I am stuck in one numerical question because I want to Have ESUNi values,Lmax,Lmin etc
Thank you for your message. All the information is provided in the MTL text file, which is downloaded along with satellite bands.
I couldn't find Lmax,Lmin value...
I have been surfing the site since long.....
