fractional land use

[bbakernoaa]

I'm trying to figure out how to calculate the fractional land use cover using land cover dataset (lets just say this one:

ftp://ftp.star.nesdis.noaa.gov/pub/smcd/JPSS/VIIRS-AST/VIIRSSurfaceType4EMC_2020Nov/VIIRS_GST_2012to2019v3L2_20types_30arcsec.nc.gz

(note it isn't actually zipped its a mistake)

I want to calculate fractional area used by each land use type in each cell. Lets say that the projection is

'+proj=lcc +lat_0=38.5 +lon_0=-97.5 +lat_1=38.5 +lat_2=38.5 +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs +type=crs'

I would recommend updating your question following the guide given for gis.stackexchange.com:

When seeking help to debug/write/improve code always provide the desired behavior, a specific problem/error and the shortest code (as formatted text, not pictures) needed to reproduce it in the question body. Providing a clear problem statement and a code attempt helps others to help you.
