Group 06 progress
• Made plan about what to do next – Search surface parameters for coniferous forest
and grass
– Do some test rounds
– Download soundings from spring and summer 2009
– Run the model with each day’s sounding trough the period
– Automatize this with script
– Calculate forest fire index using temperature, wind speed, humidity and precipitation
Surface parameters
• Coniferous forest
– Roughness: 0.5
– LAI: 3
– Albedo: 0.13
– Emissivity: 0.98
• Grass
– Roughness: 0.01
– LAI: 1
– Albedo: 0.2
– Emissivity: 0.98
Results from test rounds
• If sounding is from a dry day, there are
less clouds than if the day were a moist
day.
• We have not managed to get different
results when using different surface
parameters
– It is possible that the problem is in running
the model and not in the model itself
Script
• #!/bin/bash AROMdir="AROM_60s_L41_Jokioinen" gradspath="$MU_OUT/$AROMdir/grads" gfile="" cd $MU_IN/Jokioinen for soudate in `ls|grep html|tail -n 2|cut -c 11-21` do Sou2MUSC.sh Jokioinen $soudate Aca2MUSC.sh Jokioinen_L41 cp name* MUSCIN* $MU_WD cd $MU_WD ./Runmusc_acatest Jokioinen cd $MU_OUT lfa2ascii_hourly.sh $AROMdir convert_to_grads_hourly.sh $AROMdir cd $gradspath for luku in 1 41 42 do gfile="output_${luku}_hourly" mv ${gfile}.ctl ${gfile}_${soudate}.ctl mv ${gfile}.grads ${gfile}_${soudate}.grads done done
Script already runs without errors, but it gives same result for both test days, so it needs to be fixed.
Plans for future
• Do more test rounds
• Investigate the script
• Gather soundings
• Run model with different soundings, if everything goes well

The use of MUSC to provide minute-resolution forecasts at some Irish locations
Sinéad Duffy, Noelle Gillespie, Emily Gleeson
Update Summary
1. In addition to Dublin Airport, we tested MUSC at other station sites to view whether bias in temperature also existed – we used hourly and minute observation data.
2. Found the source of the temperature bias.
3. Had a look at temperature profile data for Harmonie and MUSC.
4. Looked into the MUSCIN* files with a view to modifying them.

Harmonie data
Reason for the bias in the MUSC data – Observation and Harmonie data = 2m temperature but the MUSC PTS parameter is surface temperature and not the 2m temperature. *** We have not found a way to get T2M from MUSC yet but I guess gl can do it….

Harmonie data

Just to show the good agreement between 3D Harmonie and Observations
3. Dublin Airport: Temperature Profiles
Left: Used Harmonie data (analysis and 3hr forecast files for 00,06,12,18 Feb 7-10th) for Dublin Airport location (x-axis = hours); right: MUSC forecast data generated by using the Harmonie files i.e. we ran a series of 3hr forecasts (minute resolution but hourly averages are plotted) using each Harmonie file.
4. Modifying MUSCIN* files
•In Har2MUSC.sh we changed the MUSC output format from OUTPUT_FORMAT = 'MUSC_FORCING_FA' to OUTPUT_FORMAT = 'MUSC_FORCING' as this yields an ASCII file in a similar format to the defatm* files in the test cases. &NAM1D • LMAP=.F. • ZDELY=250000., • LNHDYN=.FALSE., • LALAPHYS=.T., • LREASUR=.T., • NFORC= 3 -------------------- there is 3hr forcing in the file (previously we thought that there was none) • LQCGRP = T ----------------- cloud water is turned on • LQIGRP = .F. -- all of these (ice, snow, rain, graupel etc) should be T as data exists for them or else the arrays should not be included in the file • LQRGRP = .F. • LQSGRP = .F. • LQGGRP = .F. • LCFGRP = .F. ---- this should also be T when using ACAF1D.F90 to convert back to FA for MUSC experiments (i.e. that there are clouds) • LSRCGRP = .F. • LTKEGRP = .F.
4. Modifying MUSCIN* files
•In the test cases the defatm* files contained model level U, V, T, QV, then forcings and at the end aerosols, albedos etc.
• Our equivalent MUSCIN* file generated from a 3D Harmonie file is different and hence the Aca2MUSC.sh script will not work on it unless the data file is altered or the F90 code called within Aca2MUSC.sh is adjusted.
•Differences in our file: -extra parameters pressure departure, vertical div - cloud liquid, ice, rain, snow, graupel, TKE – all non-zero
Next Steps
• Consider MUSC minute data and generate temperature
profiles.
• Expand the model-level analysis to other parameters.
•Revisit comparisons to observations.
• Work on converting the MUSCIN* Ascii file back to FA
following edits.

Estonia group 2: Marko Zirk, Hardi Teder, Hannes Keernik (Andres Luhamaa)
Task - to find out, how much does surface type influence other parameters, specific attention on bog
Surprisingly, wind in forest is stronger than in bog, though slightly, or is it more like noise?
