Headlines
- Difficulties
with respect to the assimilation of OPERA volume data have been further elaborated
by the OUG (OPERA User Group), OPERA PM and the C-SRNWP PM.
- New
numerical tests are under planning to validate the quality of the foreseen
additional (06 and 18 UTC runs) ECMWF ENS BCs.
- The
new data policy for the SRNWP data pool (opening the access to
universities / academia) has been approved by the non-EUMETNET members, the terms of use have been updated on the
portal to access the data.
- The
ALADIN Assembly approved the funding for the maintenance / development of
the GLDB (Global Lake Data Base) for 2015.

Status of programmatic targets
The main activity of the C-SRNWP programme is the scientific and technical (operational)
coordination between the five LAM Consortia in Europe (ALADIN, COSMO, HIRLAM,
LACE and Met Office). The coordination is ensured by the eight Expert Teams
(data assimilation and use of observations; diagnostics, validation and
verification; dynamics and lateral boundary coupling; link with applications;
physical parameterization: upper air; predictability and EPS; surface and soil
processes: model and data assimilation; system aspects) established in 2008 and
through the regular correspondence, including the annual meeting, between the
members of the SRNWP Advisory Expert Team Committee (previously called Advisory
Committee), which consists of the consortia heads and the Expert Team chairs.
Standing for the success of the EUMETNET programmatic targets, coordination
with other Forecasting (SRNWP-EPS, Nowcasting) and
Observation (EUCOS, OPERA) Projects/Activities is done. During the first
quarter of 2014 the following coordination efforts have been made.
Coordination with
OPERA for enhancing radar data assimilation
C-SRNWP PM triggered an e-mail exchange between
OUG (OPERA User Group) members and the OPERA PM, to understand the foreseen
difficulties with respect to the deliverables OD1 and OD3 (quality flagging and
redistribution of volume data). Radial wind data will be sent to ODC by almost
all NMSs till the end of 2014, which is a basic condition for OD1 and OD3. For
the radial wind the heterogeneity of the radar instruments (different Nyquist intervals) will require the use of de-aliasing
tools. For the reflectivity data the main difficulty is to relax the current
filtering to allow a distinction between cluttered data and dry pixels (which
are currently treated both as “nodata”). This
prevents the use of valuable dry information from radars in order to correct
spurious humidity and precipitation present in the model. A proper treatment of
the problem requires to go back to the radar providers
and to change / upgrade the signal processor of radars. This fact may slow down
the achievement of OD1 regarding reflectivity and the estimation of the delay
is very uncertain (by the end of 2014 only 15 % of the radars will have these upgardes) due to the heterogeneity of the European radar
network. An alternative fast solution is to send both filtered and unfiltered
reflectivity data to ODC and do a filtering there. This latter solution would
be possible for the 80% of the OPERA members by the end of 2014 from a
technical point of view, however the bandwidth
requirements for this solution have to be still analyzed. Several NMSs started
to perform data assimilation experiments with the currently available volume
data. The experiences and feedbacks are being collected.
Coordination with
ECMWF regarding the extension of IFS EPS boundary conditions for very high
resolution EPS systems
During 2013 based on the requirements of the
SRNWP EPS community and numerical experimentations, a proposal has been
prepared for the TAC subgroup for the revision of the Boundary Condition (BC)
Optional project of ECMWF. The proposal contains two options, both as an
extension of the current BC project:
- 2
extra runs of IFS ENS (at 06 and 18 UTC) with present resolution
(including the planned upgrade in 2015), 6 days forecast range, 50+1
members, hourly output (this last also for the operational 00 and 12 UTC
runs)
- 2
extra runs of IFS ENS (at 06 and 18 UTC) with present resolution (included
the planned upgrade in 2015), 50+1 members up to a 3 day forecast range,
then 20 + 1 members up to 6 day forecast range, hourly output (this last
also for the operational 00 and 12 UTC runs)
The TAC subgroup and ECMWF proposed further
numerical experimentations to validate that the quality of the LAM EPS
forecasts coupled to the additional 06 and 18 UTC ECMWF ENS BCs. In the first
quarter of 2014 the agreement on the LAM experimental framework has been
ongoing with the help of the EPS Expert Team. ECMWF started to set up the
additional 06 and 18 UTC global test runs.
SRNWP data pool for
universities/academia
The new data policy for the SRNWP data pool
(open up the access to universities) has been approved by Assembly in November
2013 and by the two non-EUMETNET data providers (ARPA-SIMC and Roshydromet) in January 2014. The new data policy and terms
of use has been uploaded to the website for accessing the SRNWP data pool.
Support for the Global
Lake Data Base
The COSMO consortium covers the maintenance and
development costs of GLDB for 2014 (see Q4 report 2013). Recently the ALADIN
Assembly approved that the GLDB maintenance / development will be funded from
the ALADIN consortium budget in 2015.
