Radiative-kernels

Netcdf files containing data for radiative kernels.

Ozone kernel data

3D-fields with normalized radiative forcing values for gases and aerosols.

• The file NFRO3v6_OsloRF.nc contains radiative kernel data for ozone.

• The file NFRO3v6_TOA_OsloRF.nc is the same as NFRO3v6_OsloRF.nc except that it is for top-of-atmosphere (TOA) forcing instead of tropopause.

• The file aerocom.OsloCTM2.A2.CTRL.monthly.levelheight.nc specifies the monthly pressure and level heights of the ozone kernel

The data are documented in the article Skeie et al. 2020 and and Collins et al. (in prep.)

PDRMIP kernel data

• The file pdrmip_toa_rtkv2_albedo_T42_monthly.nc include radiative effects from surface albedo changes, and pdrmip_atm_rtkv2_albedo_T42_monthly.nc is the atmospheric radiative heating kernel for the same.

• The file pdrmip_toa_rtkv2_surfdT_T42_monthly.nc include radiative effects from surface temperature changes, and pdrmip_atm_rtkv2_surfdT_T42_monthly.nc is the atmospheric radiative heating kernel for the same.

• The file pdrmip_toa_rtkv2_vertdT_T42L60_monthly.nc include radiative effects from atmospheric temperature changes, and pdrmip_atm_rtkv2_vertdT_T42L60_monthly.nc is the atmospheric radiative heating kernel for the same.

These data are documented in the article Myhre et al. 2018

Aerosol direct radiative forcing kernel

• The file VP_NRF_4D_L60_V2_MM.nc contains 4D fields (lon, lat, lev, month) of normalized direct radiative forcing per unit aerosol mass, for three species:
  • nrf_bcff: BC aerosols from fossil fuel emissions
  • nrf_oc: Organic carbon aerosols
  • nrf_so4: Sulfate aerosols

The calculations and the radiative properties assumed for the aerosols are documented in Samset and Myhre 2011, GRL
