1 UEAs – strategic overview for EORO4M activities UEA (through) its activities within WP1 will provide updated/enhanced 0.5 x 0.5° gridded climate fields (see later presentation for listing of these). These grids are for global land areas (minus Antarctic). The grids will complement the other similar observed and reanalysis outputs and will be used extensively within EURO4M. There will be inter- comparisons and mergers with other products. There are a few issues to consider here: We need to define a European window Is a resolution of 0.5 x 0.5° sufficient? – we could go to a finer resolution We could produce an enhanced version of the grids for Europe (involving more input observations) – but -> We need to decide whether to include all possible additional data in an enhanced run or is it better to use additional data resources for validation exercises?

2 Considerations for UEAs input to WP2.5 In conjunction with MO and those producing reanalysis output (ECMWF), UEA will work towards improved reanalysis products through improved input data (with respect to homogeneity and missing early data etc.). This will also involve the incorporation of additional observations – including those from high quality: Satellite and radio-sonde datasets Surface data (daily T + Pressure) There are a few questions at this point: To what degree can the improvement of reanalysis input data be confined to our European window of interest (to reduce the work load)? How do we best access the surface reanalysis input data? How will MO and UEA divide the work on this?

3 A reminder of the work package description for WP1 Objectives further develop station-based gridded datasets for Europe in its entirety and selected sub-regions assess the capacity of additional satellite-derived data for climate monitoring (linked to the EUMETSAT-SAFs), examining the parameters to be monitored, drawbacks and strengths of the methods and approaches used, the capacity for monitoring patterns of anomalies in time and across space, the capacity for trend analysis, and the capacity for the appropriate merging of satellite data with ground-truth (i.e. in situ based observations); provide gridded satellite-based datasets for ECVs, in particular those part of the energy-water cycle, such as water vapour, components of the radiation budget at the surface and cloud albedo; work with existing data recovery, rescue, imaging and digitisation activities to improve and temporally extend the ECV databases for the European region (linking with WG1 of the international ACRE initiative plus EuroCryoClim in the Arctic, EUMETNET-ECSN for Europe, and MEDARE for the Mediterranean), in order to coordinate and make accessible currently available historical climate data; conduct a comprehensive European climate data survey to identify the specific strengths and deficiencies in both the current atmospheric observation system and historical data availability (linking with WG1 of the international ACRE initiative), focusing on the GCOS ECVs; foster coordinated approaches to standards-based data management across climate-related data centres, including developing best-practice approaches for metadata, data, and services.

14 EURO4M UEA Contribution to WP1.1

15 0.5 x 0.5° resolution monthly gridded fields from observed data CRU will update the latest version of the 0.5 x 0.5° global time- series grids for pre, wet, dtr, vap, tmp, tmn, tmx and cld. These add to the pool of surface observed and reanalysis resources which will be used extensively within EURO4M. Further updates will be real time. Added to the above variables will be pet (potential evapotranspiration) and PDSI (Palmer drought severity index). For a flow diagram showing the processes towards the updating of the 0.5° grids, see next slide. CRU will produce an update paper for Mitchell and Jones (2005). We will likely have to make all the software and all data available BUT we will not be providing a help desk for outside interests to get their package to work.

19 EURO4M DWD Contribution to WP1.2 (Developing gridded datasets based on long-term remote sensing data)

20 CM-SAF will contribute raster data of ECVs to EURO4M. Parts of the gridded data are derived by data fusion of in-situ measurements, satellite observations and re-analysis data. This approach will keep the benefits of the individual data sources and will minimize the drawbacks of each individual data set. Two examples: 1. Data fusion of GPCC in-situ based precipitation over land with HOAPS satellite based precipitation over ocean. GPCC is not available over water, HOAPs is not available over land. 2. Data fusion of ERA thermal surface radiation budged with satellite based surface solar radiation budget in order to provide a best of product. Re-analysis is accurate in the thermal region but the satellite based data has a higher accuracy in the solar spetrum.

21 Example (monthly mean) of the surface radiation budget gained by combination of satellite based data and NWP analysis data (here GME).

22 CM-SAF will also provide stand-alone satellite based data which is only observable from space, e.g.. - Top of atmosphere albedo - Cloud albedo & other cloud parameter. Example of the reflected solar irradiance at the top of atmosphere. Monthly mean, June 2008.

23 CM-SAF will also provide stand-alone satellite based data which is only Observable from space, e.g. - Top of atmosphere albedo - Cloud albedo & other cloud parameter ! 10 year mean of monthly mean cloud albedo for June.

24 CM-SAF will also provide raster for climate protection applications. E.g. solar surface irradiance, which is needed for a efficient planning and design of solar energy systems. Transparent solar cell and traditional PV system. Example of a solar surface irradiance map used for solar energy potential studies and Planning of PV systems.
