Hirlam Project – Data Assimilation
3DVAR in operational models. Assimilation of GPS data (TOUGH project). Test of Hirlam 4DVAR in the Cray X1e. Soil moisture analysis comparison
between Hirlam reference system and 1DVAR version (ELDAS project).
Mesoscale Rapid Update Cycle of analysis of surface parameters.
Assimilation of VAD winds from INM radar network.

Spring period: 15 April-15 May 2004
Impact of introducing 31 new GPS sites
ETS and TSS show that increasing the number of GPS sites improves model precipitation.
Verification with INM Climate stations (upscaled to 22km).
PP thresholds (0.1, 0.3, 1., 3., 10., 30., 100. mm in 24 hours)

Hirlam Project – Dynamics
Different strategies of coupling dynamics-physic in Hirlam.
Stability and same meteorological quality with larger time step.

Hirlam Project – Physics
Surface processes: Snow OI analysis. ECOCLIMAP database in Hirlam. New formulation of snow processes
using two additional tiles: snow over open land Snow over forest

19
Hirlam Project – Physics
Convection: New moist scheme based on Kain-Fritsch
convection and Rasch-Kristjannsson large scale implemented into the HIRLAM reference system.
Forecast 10-20 % more expensive and even more on vector computers (vector optimization in progress).
Improvement of precipitation over Iberia.
