Ludwig-Maximillians-Universität (LMU) München
GOP Characteristics
 General Observation Period from January to December 2007
 Comprehensive data set suitable for testing hypotheses and new modeling
techniques developed within the QPF-Program.
 The GOP encompasses COPS both in time and space
- to provide information of all kinds of precipitation types and
- to relate the COPS results to a broader perspective
(longer time series and larger spatial domain)
GOP Observations
 Optimized exploitation of existing instrumentation
no funding for instrument development or upgrade
- routine measurements normally not available to the scientific community
- continuous/coordinated operation of existing instrumentations
suitable for statistical evaluation
 Focus on measurements which are available in near real-time
near-realtime analysis + first-order model evaluation
 Rigorous quality control, cross-checking
and error estimation
Provision of coordinated
observations and model
output to SPP projects
 Easy access to data, quicklooks and analysis
(VERIPREC, STAMPF,
DAQUA, QUEST,...
 Close connection with COPS activities
WG "Precipitation Process" & data management
Personnel funding for observations only when instruments are moved to other locations
GOP Precipitation Observations
 High resolution surface precipitation (rain gauges)
DWD, various water authorities, environmental
agencies and urban networks
 3-D hydrometeor distribution (weather radar)
-16 C-band DWD radars
- polarimetric research radars: POLDIRAD, DLR;
DWD Observatory Hohenpeissenberg
- C-Band radar Karlsruhe; X-Band radars Bonn & HH
- operational radars in neighboring countries
 Rain drop size distribution (RDSD)
- network of vertical pointing Micro Rain Radar (MRR)
- in situ disdrometer
Joint objective of COPS WG3 & GOP
Investgation of the differences of the
RDSDs over flat terrain including
maritime conditions on one hand and
over orographically structured terrain
on the other hand

GOP & COPS
GOP
 to provide information of all kinds of
precipitation types
 to identify systematic model deficits
 to select case studies for specific
problems
 to relate the COPS results to a
broader perspective (longer time
series and larger spatial domain)
MRR transsect will be coordinated with
POLDIRAD RHI scans during COPS
GOP Network Observations
IWV [kg m-2]
 Integrated Water Vapor (GPS)
about 180 stations within Germany
about add. 40 in neighboring countries
process more french stations
set-up of 5 stations in COPS area for 6 months
to get a better estimation in the structured terrain
 Cloud and aerosol vertical information
(Lidar networks)
- lidar ceilometer observations from institutes & DWD
> 100 in Germany
- coordinated (regular scheduled) EARLINET
(Hamburg, Leipzig, Munich, Garmisch, Cabauw,
Neuchatel..) with a high quality standard to derive
statistical aerosol properties
 Lightning detection systems
- Conventional lightning detection system (BLIDS)
- VHF network in Northern Germany
- VLF LINET system in Southern G.

Statistical evaluation of water vapour, cloud and precipitation structure
 extraction of station output (rain gauges, MRR, GPS, ..) together
with model output and online visualization
 diurnal cycle on a monthly basis of all parameters
time series at station and maps
 convective/frontal
 cell tracking
 vertical structure (hydrometeor distribution)
 regional characteristics
 sub-grid properties

GOP Preparation
 Establishment of the data base
- coordination with DWD and data owners
- coordination with COPS campaign data
how to set-up and how to get funding
 Quality control of the observations
- rain gauge estimates (UniBonn)
- radar and satellite observations (QUEST)
- joint effort of data owners
 Tailoring model output to data available from GOP
- definition of model domain, horizontal resolution, boundary conditions...
- focus on Lokal-Modell-kürzestfrist (LMK)
 - preparation of special model output (integration into NUMEX)
→ time series in model time step resolution at selected stations
→ selected 3D-fields at asynoptic times for satellite/radar comparisons
- online visualization of statistical properties from model and observations
(diurnal cycle, PDFs,..)
• long-term evaluation
• identification of case studies
