Inputdata

Temperature (temp) Data:

------------------------

CIRA 86 (Fleming et al, 1990)

 

Vertical interpolation to 1km level spacing

Horizontal interpolation to 5 deg latitude interval

 

 

 

Ozone (o3) Data:

----------------

FUB-ozone climatology (version 02, updated from

Fortuin and Langematz, 1994), at 5 deg latitude intervals

CIRA satellite climatology, combined with tropospheric

ozone sonde data

 

At 5 deg latitude intervals

Vertical interpolation to 1km level spacing

 

 

 

Methan (ch4) Data:

------------------

HALOE observations above 13 km, at 5 deg latitude intervals

(Data provided by C. Bruehl, MPI Mainz)

 

Above 80 km constant values.

Below 9 km constant value of 1.7 ppmv,

also set to 1.7 ppmv in tropical upper troposphere (15S-10N

13-14km) to supress unrealistic values in this region.

 

Vertical interpolation to 1km level spacing

Interpolation between 9 and 13 km

Time interpolation from 2-month-means to the 15th of January

 

 

 

Water vapour (h2o) Data:

------------------------

HALOE observations above 12 km, at 5 deg latitude intervals

(Data provided by C. Bruehl, MPI Mainz)

Time interpolation from 2-month-means to the 15th of January

 

NCEP/NCAR global reanalyses below 8 km

(Data provided by D. Shea, NCAR)

 

Horizontal interpolation to 5 deg latitude interval

Vertical interpolation to 1km level spacing

Interpolation in transition region

 

 

 

Albedo:

-------

Values from Berlin CMAM  

In the model, albedo depends on surface charcteristics

(land, sea, ice, vegetation)

Mean of 30-day integration under perpetual January conditions

 

Horizontal interpolation from 5.6 x 5.6 to 5 x 5 degrees

 

 

 

Zenith-angle:

-------------

Cosine of zenith-angle computed by the Berlin CMAM

Values for daily mean at the 15th of January

                                        

Horizontal interpolation to 5 deg latitude interval
