ELDAS 2nd progress meeting
Radiation and heating rates
• ELDORADO– Database delivered to ECMWF &
Alterra– Paper (Meetschen et al) submitted– KNMI Preprint
![Page 10: ELDAS 2nd progress meeting INM Madrid, 10 & 11 dec 2003.](https://reader036.fdocuments.net/reader036/viewer/2022062302/5a4d1b217f8b9ab0599958f7/html5/thumbnails/10.jpg)
ELDAS 2nd progress meeting
Heating rates workplan
• Gisela’s scm-study MUREX:– METEOSAT info consistent with local Tskin
measurements, but too low sampling frequency
![Page 11: ELDAS 2nd progress meeting INM Madrid, 10 & 11 dec 2003.](https://reader036.fdocuments.net/reader036/viewer/2022062302/5a4d1b217f8b9ab0599958f7/html5/thumbnails/11.jpg)
ELDAS 2nd progress meeting
Heating rates workplan
• Gisela’s scm-study MUREX:– METEOSAT info consistent with local Tskin
measurements, but too low sampling frequency• 2000 database prepared
– Additional info on obs.error stil to be added• Case study with 2003 in progress
– 3 months (May-July)– METEOSAT and MSG– Simple data assimilation in RACMO– If successful & feasible: ECMWF will use 2000
database
![Page 12: ELDAS 2nd progress meeting INM Madrid, 10 & 11 dec 2003.](https://reader036.fdocuments.net/reader036/viewer/2022062302/5a4d1b217f8b9ab0599958f7/html5/thumbnails/12.jpg)
ELDAS 2nd progress meeting
Database for 2003• Originally intended for MSG demonstration• No full data assimilation experiments
foreseen within ELDAS• However: forcings database will enable
future heating rate pilot exps prior to operational implementation: presence in MARS very helpful!
• Anticipated period: 1 May-1 Aug 2003– Precip?– ELDORADO: ok– Heating rates: ok

ELDAS 2nd progress meeting
New GLDAS/BALTEX workplans
• GLDAS-wp (4300):– Original: Evaluate ELDAS over US basins– New: over 2000 Europe:
• GLDAS: offline VIC-simulation (well-calibrated hydrologically oriented surface scheme)
• ELDAS1: offline TESSEL-simulation• ELDAS2: assimilated run• Optional: use GLDAS precip dataset (currently not
yet available for 2000)– ELDAS1 – GLDAS: 2 surface schemes driven
as in GLDAS (no data assimilation)– ELDAS2 – ELDAS1: added value of data
assimilation
![Page 18: ELDAS 2nd progress meeting INM Madrid, 10 & 11 dec 2003.](https://reader036.fdocuments.net/reader036/viewer/2022062302/5a4d1b217f8b9ab0599958f7/html5/thumbnails/18.jpg)
ELDAS 2nd progress meeting
New GLDAS/BALTEX workplans
• Baltex wp (5400)– Original: use 18-year dataset to compare
to ELDAS climatology (unfeasible)– New: as in previous wp: use both offline
& full simulations to compare to discharge dataset, assessing• Intermodel differences• Added value of data assimilation• Added value of high resolution precip forcing
![Page 19: ELDAS 2nd progress meeting INM Madrid, 10 & 11 dec 2003.](https://reader036.fdocuments.net/reader036/viewer/2022062302/5a4d1b217f8b9ab0599958f7/html5/thumbnails/19.jpg)
ELDAS 2nd progress meeting
New GLDAS/BALTEX workplans
• Required:– Offline forcing over Europe (ALMA netCDF
standard)• From MARS-archive• To be compiled by SMHI
– Offline simulation of VIC• To be carried out by SMHI in context of workvisit UW
– Offline simulation of TESSEL• To be carried out by KNMI
– Analyses: as planned• GLDAS-wp: KNMI• BALTEX-wp: SMHI

Info on soil hydrological memory from reanalysis
& discharge• P – E = R + dS/dt
