Scope and purpose of workshop: A workshop to build on the blend of the US Comprehensive Ocean-Atmosphere Data Set (COADS), with the UK Met. Office Main Marine Data Bank (MDB), plus with newly digitized data in the US and from other international partners. The blend, encompassing 1784-1997, will provide the climate research community with an unprecedented assembly of in situ marine data. Sea surface temperature (SST) measurements will be an important topic. A key focus of the meeting will be on the work of the SST and Sea-Ice Working Group (SST/SI WG) of the GCOS/WCRP Atmospheric Observation and Ocean Observations Panels for Climate (AOPC/OOPC), as well as new NOAA initiatives in the SST area. After SST, other crucial climate variables are to be considered (in priority order):

* sea ice concentration and extent

* nighttime and daytime marine air temperature (MAT)

* sea level pressure

* wind

The discussions of sea level pressure and wind data will be coordinated with the Mean Sea Level Pressure Working Group recently set up through the GCOS/WCRP AOPC.

Main goals:

· Create a timetable for enhancing in situ marine datasets in more than one phase, taking account of plans for further digitization of data.

· Develop a strategy for creating alternative SST, sea-ice and marine air temperature analyses, including appropriate satellite data, to test models against the legitimate uncertainties in "reasonable" alternative analysis methods.

· Consider strategies for the joint analysis of surface pressure and wind data, taking account of time-varying biases in the wind data.

· Make recommendations for blending appropriate marine and land-based data to achieve globally complete surface data sets.

· Take account of recommendations made by the CLIVAR Climate of the Twentieth Century Project, where a key component involves AGCMs being forced with observed SST and sea-ice extent by around 11 groups.

Participants: Members of the SST/SI WG, plus research groups active in the assembly and processing of historical marine data, and of products for SST/SI and other variables (by invitation).
