Major upgrade of SEISMIC to extend to the whole of Great Britain - PS2225

The SEISMIC environmental information and scenario mapping system has been in use by staff of DEFRA, the Pesticides Safety Directorate and member companies of the British Crop Protection Association since December 1994. It is used to support pesticide approval applications and evaluations. SEISMIC enables users to map the distribution of specific soil, crop and climate scenarios within England and Wales and access the detailed soil and climatic data required to model the environmental fate of pesticides for that scenario. In 1998, an upgraded version of the system (v1.5) was developed to add statistical summary functions for mapped scenarios and to include the most recently available cropping statistics for the year 1995. The system was further upgraded in 2003 to a windows-based system with the incorporation of spatial groundwater (v2.0) and aquatic ecosystems (v2.5) data sets.

It is now proposed to create v3.0 of SEISMIC - extending it in a major way to cover the whole of Great Britain by incorporating data from Scotland, upgrading and extending the climatic data inputs and developing GB-wide pedotransfer functions.

This will benefit all those involved in the research, management and regulation of environmental resources. By extending the coverage nationally, SEISMIC will provide a more complete spatial environmental information system and enable the modelling and evaluation of the fate of pesticides throughout England, Wales and Scotland. By evaluating climate and soil properties on a GB-wide basis, cross border methodoligical inconsistencies will be eliminated.
1. To derive spatial data sets for each 5km by 5km grid cell for Scotland relating to:
a. Soil Series
b. Climate (including England and Wales)
c. Aquifers

such that compatible and seamless spatial data is provided across the whole of Great Britain within the SEISMIC data framework.
2. To derive non-spatial soil series classification data for Scotland relating to soil subgroup, Hydrology of Soil Types (HOST) class, Soil textural classification, Crop type, General leaching potential ,Organic chemical leaching potential and Organic chemical run-off potential such that a compatible and seamless non-spatial soil data is provided across the whole of Great Britain within the SEISMIC data framework.
3. To derive non-spatial soil series attribute data on soil layers (to a depth of approximately 1.5 metres) for each of the broad land use categories (arable, long ley pasture and semi-natural vegetation) for each of the main soil horizons. These data will include information on soil horizon:
a. Nomenclature, depths, texture, Organic Carbon (%), pH and Bulk Density
GB-wide pedotransfer functions will be developed, such that values for
b. Total porosity, Water Content at 10, 40, 200 and 1500 kPa and Saturated Hydraulic Conductivity
can be calculated and incorporated into the SEISMIC data framework.
4. Daily weather parameters from a set of weather stations, representative of the main Scottish agricultural areas, will be generated and included within the model:
5. To incorporate into the SEISMIC system the data sets produced from objectives 1 through 4 and to test and debug the system.
