years used for climatological SST

[weili@psu_edu]

Hi CAM users,

Is there anybody know the years that used to calculate the climatological SST
of CAM? For example, sst_HadOIBl_bc_1.9x2.5_clim_c040810.nc. It is the climatology of which period? Where can I find this information?

Thanks.

The climatologoly was computed over the years 1982-1001.

Thank you hannay. I noticed that for a specific resolution, there are more than one version of climatological sst. For example, FV1.9, there is another sst_HadOIBl_bc_1.9x2.5_clim_c061031.nc. It is also calculated from 1982-2001 or other years?

Also, which years are used for these SST for T42 and T85?
sst_HadOIBl_bc_64x128_clim_c020411.nc
sst_HadOIBl_bc_64x128_clim_c050526.nc

sst_HadOIBl_bc_128x256_clim_c031031.nc
sst_HadOIBl_bc_128x256_clim_c050526.nc

From where can I know this information?

Thanks!

All the climatologies are computed with the same set of years: 1982-2001

One place you can find some information is in the code to compute the climos.
This is in: models/atm/cam/tools/icesst

The README file tells the set of years the code uses to compute the climos:

One important note on the climatological averaging period. In general the
namelist variables defining it should NOT change from 1982-2001. The code
checks for this and errors out if the values are set inappropriately. It
also prints a message explaining how to change the climatological averaging
period if the user really wishes to do so.
