2. Issues for Coastal Oceanography and Inland Hydrology Data sets to be used – here we use the US west coast. Time and space scales to be resolved. Use of tide gauges. Use of alternate corrections (wet tropo). Help from numerical models of coastal circulation.

3. Altimeter Issues For Coastal Oceanography Time and space scales to be resolved. ~ 1-5 days; 10 km offshore; 300-500 km alongshore Use of tide gauges can help. Use of alternate corrections (wet tropo, etc.) are needed. Need some in water current measurements. Help is needed from numerical models of coastal circulation.
