Surface UV maps

Bodeker Scientific plans to construct a daily database of surface radiation fields (including UV-A, UV-B and Photosynthetically Active Radiation (PAR)) for the high latitudes of the Southern Hemisphere (>40°S) from 1979 to 2100 to meet the needs of the national and international Antarctic biology communities to assess past, present and projected future impacts of changes in incident radiation on Antarctic ecosystems. The proposed data sets of surface radiation will be constructed by first modelling surface clear-sky radiation using a radiative transfer model. Ozone fields required as input to the model will be obtained by extending an updated version of our total column ozone database with projections of future ozone changes obtained from a suite of chemistry-climate models (CCMs). A sophisticated method, based on climate pattern-scaling and empirical orthogonal function analysis, will be used to combine the forced signal of change in total column ozone obtained from the CCM simulations with statistically realistic (both in space and time) fields of ozone variability derived from observations. An algorithm for estimating surface irradiance in the presence of clouds will then be used to convert clear-sky radiation fields to more realistic cloudy-sky radiation fields. For the past, cloud fields will be obtained from the International Satellite Cloud Climatology Project (ISCCP). For the future, because clouds fields from Atmosphere-Ocean Global Climate Models (AOGCMs) are unreliable, changes in cloud occurrences obtained from AOGCMs will be used in a manner similar to that used in which CCMs are used for total column ozone, to generate statistically realistic changes in cloud cover that follow trends obtained from AOGCMS.

Bodeker Scientific recently applied for funding to undertake this work but was unsuccessful in part because 'the proposal is about developing a database but the potential users are not identified'. Therefore, in preparation for a second attempt at applying for funding for this work, we are looking for letters of support/interest that:
  1. Indicate the interest of a research group in using this database.
  2. Indicate an interest in collaborating with Bodeker Scientific on the exploitation of such a database in the field of Antarctic biological research.
If you are willing to provide such a letter that would be very much appreciated. Including additional detail as to how this database may serve your purposes would be great. Furthermore, if you are aware of other research groups that would be interested in this database, please do not hesitate to pass the URL for this webpage on to them. Letters of interest should be sent to Greg Bodeker ( These letters will then be included in the revised funding proposal.
