Timestamp incorrect netCDF (Sentinel atmospheric Data)

A_n_d_r_e_a — Sun, 14 Mar 2021 13:13:54 GMT

Dear Community,

i want to do an multidimensional air pollution analysis. I downloaded some netCDF Data from the Copernicus CAMS website.

I choose there the timestamps from 01.01.2019-30.06.2019 in hourly steps.

But if i load them as multidimensional layer in ArcGIS Pro there are completely other timestamps from1899 etc. Thats not what I downloaded from the copernicus website. I uploaded a picture with my problem.

What can be wrong?

Thanks forward!

Greetings,

Andrea

Can you look at the headers for those files? The unit of measure may be specified as

measureTS:units = "day since 1899-12-30T00:00:00 UTC"

so you may have to standardise the temporal UoM. But more of a guess than anything else.

Hi David,

okay in the table viewer is also the incorrect date. Instead of 2019 it`s1979.

But why...
