Those specific values can be found in the meta data of that specific file:
short geophysical_data/poc[pixels_per_line,number_of_lines] (Chunking: [37,486]) (Compression: shuffle,level 4)
long_name: Particulate Organic Carbon, D. Stramski, 2007 (443/555 version)
units: mg m^-3
reference: Stramski, D., et al. "Relationships between the surface concentration of particulate organic carbon and optical properties in the eastern South Pacific and eastern Atlantic Oceans." Biogeosciences 5.1 (2008): 171-201.
The values of the derived raster seem wrong. After outlier correction they are like this:
values: 6402.577, 6416.052 (min, max)
In general, is the procedure of first multiplying the data by the scale factor and after this adding the add offset to the values correct?
Are those 2 specific values the right ones I identified in the meta data?
Looking at the range of values for POC presented here https://oceancolor.gsfc.nasa.gov/atbd/poc/, the values I retrieve can not be correct, no? The date of my file is 01. Jan. 2018. The region is the wider Indo-Pacific. So, not just a small area with potentially exceptionally high POC values.
How can I solve this problem to retrieve correct Particulate Organic Carbon values from the nc file? Thanks!
