Proposal for provision of model data to the PROMISE Users
1. Current climate scenarios
a. Climate integrations, minimum
of 30 years, 1966-19951
b. ERA-40, 1957-2001
c. Seasonal prediction ensembles from DEMETER, 1987-2001 available by
end 2001
1 To include overlap period with AMIP II.
2. Future climate scenarios
a. 2010-2039 to exploit land
use change scenarios
b. 2040-2069 for CO2 induced climate change2
2Do we need to agree which CO2 scenario should be used?
3. Minimum model output
Based on that proposed by DEMETER and taking into account the need of the water resource and crop modelling groups. Symbols and units are as used in AMIP II standard output. (NB. Units3 may differ slightly from those used in DEMETER and the GRIB archive.)
3.1 Output every 24 hours at 00Z:
3.1.1 Pressure level (850,
500, 200hPa) data (instantaneous):
| Zonal wind | m/s | ua |
| Meridional wind | m/s | va |

| Specific humidity | kg/kg | hus |
| Geopotential height3 | m | zg |
3.1.2 Single level (instantaneous):
| 2m temperature maximum | K | tasmax |
| 2m temperature minimum | K | tasmin |
| Total soil moisture | kg/m2 | mrso |
| Snow depth (water equivalent) | kg/m2 | snw |

3.1.3 Single level (averaged over previous 24 hours):
| Total precipitation rate3 | kg/(m2s) | pr |
| Downward surface solar radiation3 | W/m2 | rsds |

3.2 Output every 6 hours at 00, 06, 12, 18Z:
3.2.1 Single level (instantaneous):
| Total cloud amount3 | % | clt |
| 10m zonal wind | m/s | uas |
| 10m meridional wind | m/s | vas |
| 2m temperature | K | tas |
| 2m specific humidity | kg/kg | huss |
3DEMETER archive uses geopotential (m2/s2), accumulated total precipitation (m), accumulated (not averaged) fluxes (Ws/m2), fractional cloud amount (0-1).
