A quicklook inventory will allow the PQP participants to pick case studies easily. The PQP project VERIPREG (Paulat et al. 2005) will produce hourly precipitation maps from a combination of radar (composite of precipitation scans) and in situ rain gauge data. The PQP project QUEST will use the 3D radar reflectivities to evaluate the forecasted hydrometeor distributions via forward simulation by a polarimetric radar operator. ^ Name ^ Code ^ PI ^ Location ^ Temp.

At least 13 will be located at selected sites (see map below) in order to study differences of RDSDs over flat terrain including maritime conditions on one hand and over orographically structured terrain on the other hand. A transect of MRRs will be deployed in the COPS area and coordinated with polarimetric radar (POLDIRAD/DLR) observations during COPS. Examples of actual MRR observations can be viewed [[http://www.meteo.uni-bonn.de/forschung/gruppen/mrr/mrr2_5min.html|here]]. Different surface based disdrometers are used as well: 2 Joss Waldvogel Disdrometer (JWD), 3 Optical Disdrometer ODM470, and 4 Parsival Disdrometers. These instruments are based on different physical principle and methods for retrieving DSDs and will thus help to keep the major uncertainty of MRR-based DSDs under control, namely a potential bias due to vertical wind. ^ Name ^ Code ^ PI ^ Location ^ Temp.

EARLINET will provide range-resolved aerosol profiles on a regular basis, approximately three times a week. The data (from all EARLINET stations across Europe) will be available in a data base open for the COPS community. These data include the height of the planetary boundary layer, aerosol backscatter and extinction coefficient profiles typically for one or two wavelengths (355 nm / 532 nm). German EARLINET stations include Hamburg, Leipzig, München, and Garmisch. Measurements from lidar ceilometers at more than 100 stations within Germany are available through DWD. Furthermore, data from several institutes (for example Meteorological Institutes in Bonn, Hannover, Kiel, and DLR) will be acquired. It will be investigated whether more stations can archive the backscatter profile in addition to the standard cloud base height. ^ Name ^ Code ^ PI ^ Location ^ Temp. Reso. ^ Vert.

This will provide an excellent overview of the current weather situation, on a larger scale and for the GOP and COPS area. The information is online (http://wew.met.fu-berlin.de/nrt) with a delay of 2 hours. The SEVIRI instrument on MSG with its 11 spectral channels from 0.6 to 14 μm will be the prime instrument. The calibrated satellite data are processed automatically to provide higher-order, level 2 products, such as water vapor and cloud top pressure. SEVIRI products will be adopted to monitor atmospheric products at meteorological stations within the LMK domain, e.g. Cabauw and Lindenberg, but also at COPS experimental sites, MAP stations and Berlin. In addition to the production of time series, averages of selected regions will be compared to LMK output on a regular, operational basis. Depending on the status of the upcoming satellites CLOUDSAT, CALIPSO, and METOP 1, other satellites might be utilized for validation purposes. Special observations with high resolution about stability indices will be available through EUMETSAT. ^ Instrument ^ Code ^ Temporal\\ resolution ^ Spatial\\ resolution ^ Products ^ Accuracy ^ Daily data\\ volume / MB ^ | SEVIRI / Meteosat-8 | msg_arst \\ msg_cfra \\ msg_cmas \\ msg_ctpr \\ msg_inwv \\ msg_odep \\ msg_stst | whole disc every 15min. | Δx~3 km nadir\\ Δx~5 km Europe\\ | near true color image **TCI** \\ cloud mask **CM** \\ clear sky brightness temperature **BT** \\ integrated water vapor **IWV** \\ cloud top pressure **CTP**| \\ \\ ΔTB~3.3 K \\ ΔIWV ~0.7 g m-2 (day, land, clear sky)\\ ΔCTP~52 to 121 hPa (high to low-level clouds) | | | MODIS / TERRA | sat_modi | overpass Europe ~10:30 am | Δx 0.3 - 1 km nadir | TCI \\ CM \\ cloud optical thickness **Δ** \\ liquid water path LWP\\ effective radius reff \\ geometric cloud thickness **H** \\ IWV | \\ \\ \\ ocean and warm bound. layer clouds \\ " \\ " \\ ΔIWV~0.24 g m-2 clear sky land surfaces | | | MODIS / AQUA | | overpass Europe ~1:00 pm | Δx: 0.3 - 1 km nadir | same as MODIS / TERRA | | | | MERIS / Envisat | | overpass ~10:30 local| Δx: 0.25 - 1 km nadir | TCI\\ CM\\ Δ\\ CTP\\ IWV | \\ \\ \\ ΔCTP~183 m (single low-level clouds)\\ clear sky, ocean, land and above clouds | | | CPR / [[http://www.nasa.gov/mission_pages/cloudsat/main/index.html|CLOUDSAT]] | sat_csat | launch: April 28, 2006 | | | | | | AMSU NOAA | sat_amsu | | | TB, IWV, LWP, RR | \\ \\ \\ | | ==== Meteorological stations (GOP-8) ==== The observations from meteorological stations (DWD, Meteorological and Geographical Institutes, research organizations, etc.) provide continuous information on the atmospheric state. In particular we will use data from  DWD observatories (Hohenpeissenberg, Lindenberg); especially at Lindenberg a wealth of remote sensing (radiation, microwave radiometer, ceilometer, Raman lidar, cloud radar, wind profiler, GPS etc) and in situ instrumentation is available as well as 4 radiosoundings per day. The observations will allow the characterization of the atmospheric state (in particular the boundary layer and clouds) as complete as possible. * Further observatories of diverse operators can provide information from interesting locations (UFS Schneefernerhaus; Schwarzwald Observatories Hartheim and Tuttlingen). * Observatories of foreign weather services including for example the Cloudnet sites Cabauw, Chilbolton and Palaiseau which provide information on the vertical cloud distribution. * Meteorological and also geographical institutes operate a rather complete set of instrumentation; as an example the available instruments at the Meteorological Institute Bonn consists of lidar ceilometer, microwave radiometer MICCY, infrared radiometer, micro rain Radar, X-Band Radar, Scintillometer, rain gauges, weather station. This also includes foreign institutes like the IAP Bern. ^ Name ^ Code ^ PI ^ Location ^ Temp. Reso. ^ Vert. Reso. ^ Products ^ Data/Day ^ Avail.
