Rob,

Below is a draft MoU for the proposed work. Comment at will - structure, content, realism, spelling... whatever. No doubt there are things I've misunderstood.

If you print/view it in a monospaced font and it'll all line up.

I'm charging the same daily rate I used for Elaine - hope that's alright.

Note that Dave recommends not using HadCM2 greenhouse gas plus sulphate - "the sulphate runs are shit" is his no-doubt confidential opinion ;-)

Cheers

Harry

MEMORANDUM OF UNDERSTANDING

WROK TO BE CARRIED OUT FOR CLIENT: Dr Robert Wilby

BROAD DESCRIPTION OF WORK:

Acquisition of extended European windows for model and reanalysis data,
regridding of reanalysis data to model grid resolution, calculation of airflow
indices.

DETAIL OF WORK:

1. Acquisition of model data

The following models will be used:

HadCM2 - hcgg, hcgg2
HadCM3 - A2a, B2

The following parameters are available at daily timestep, 1961-2099. A subset
will be agreed before extraction and processing begins. Suggested parameters
have been marked (*) to preserve some kind of resonance between these and the
NCEP Reanalysis data.

HadCM2 hcgg, hcgg2:
geopotential height at 1000HPa
convective rainfall (not hcgg2)
convective snowfall (not hcgg2)
mean sea level pressure (*)
total precipitation
maximum temperature (*)
minimum temperature (*)
total rainfall (not hcgg2)
total snowfall (not hcgg2)

HadCM3 A2a/B2:
convective rainfall
convective snowfall
total downward surface shortwave flux
surface moisture flux - evaporation
mean sea level pressure (*)
net downward surface shortwave flux
geopotential height at 500HPa, 700HPa, 850HPa (*500,850)
total precipitation rate
relative humidity at 500HPa, 700HPa, 850HPa
relative humidity (*)
subsurface runoff amount
surface runoff amount
soil moisture content
snow amount
specific humidity (*)
surface heat flux
large-scale rainfall rate
large-scale snowfall rate
total cloud in longwave radiation
mean temperature at 1.5m (*)
maximum temperature at 1.5m
minimum temperature at 1.5m
wind speed at 10m
maximum wind speed at 10m


2. Acquisition of NCEP Reanalysis Data

The following parameters will be acquired at daily timestep, 1961-2000:

air temperature at 2m
sea level pressure
specific humidity at 2m
relative humidity at 2m
specific humidity at 500HPa, 850Hpa
geopotential height at 500HPa, 850Hpa


3. Windowing and regridding

A fixed window will be extracted. Exact co-ordinates are still being negotiated
but will be at least 80N to 20N, 90W to 70E.

The NCEP Reanalysis Data will be on either a 2.5�x2.5� grid, or a T62 Gaussian
grid. Both will be regridded to a 2.5�lat x 3.75�lon grid, provisionally using
NCL routines from NCAR.

All data will be made available as necessary, either as whole windows or as
selected cells.


4. Calculation of Airflow Indices

A client-supplied Fortran program, 'canflow', will be adapted and used to
calculate airflow indices from each sea level pressure series (HadCM2 GG & GG2,
HadCM3 A2a & B2, NCEP Reanalysis).


COSTINGS AND TIMESCALES

The different activities have been separately treated for clarity.

1. Acquisition of model data
2. Acquisition of NCEP Reanalysis Data (Note 1)

3 days spread over 2 weeks, @ �100/day �300

3. Windowing and regridding (Note 2)

5 days spread over 2 weeks, @ �100/day �500

4. Calculation of Airflow Indices (Note 2)

2 days spread over 1 week, @ �100/day �200


TOTALS 10 days spread over 5 weeks (Note 3) �1000

Notes

Note 1
Activity 2 is necessarily dependent on the availability of data from an external
source. At present there is no reason to suppose that this will present undue
difficulties.

Note 2
Activities 3 and 4 are necessarily dependent on the correct operation of
unfamiliar external programs. At present there is no reason to suppose that
this will present undue difficulties.

Note 3
Unforseen circumstances may necessitate renegotiation of timescales. However,
every effort will be made to stay within those quoted.


PROJECT DATES

Preparatory work has begun for activities 1 and 2. Client go-ahead by 22/6/01
would give an approximate finish date of end July.
