CERRA min/max 2-m temperature on tape storage?

Is the CERRA with product type ‘forecast’ on tape storage?

I wonder since it takes 2-3 min dor product type ‘reanalysis‘ variables (e.g. 2-m temperature) to be processed (i.e. lapse time between request being updated from “running“ to “successfu“). It is just as fast for precipitation (also a forecast data type). On the other hand, it takes about 40 min to process 2-m maximum/minimum temperature.

In other words, for downloading 2 x 468 GRIB files (i.e. monthly files between years 1985 - 2023) at the current processing rate, it would presumably take > 25 days to complete the task. Is there any workaround?

Cheers, Christophe
