Great Lakes Forecasting System Laboratory: Takis Velissariou (his wife had surgery) Summary:

Xutong Niu reported that:

1- He obtained the data descriptions from Ahmed that explain the sources of the data used in the DG project.
2- He tested the remotely-access database program from Xian.
3- He visited the USGS Tampa Bay project web page.
4- He suggested building a web page for our current data and arranging the data so that it can be easily accessed and can be used as an example for government agencies.
Tarig Ali mentioned that he visited the USGS web page for Tampa Bay project. He suggested the following research topics be discovered:
1- Sediment plume mapping.
2- Water vapor mapping.
3- Sandbar detection from high-resolution satellite.
4- Tide direction mapping.
Ruijin Ma reported that he has finished the five functions for the ODNR permit system. He gave a presentation about his view of the project (Appendix A).

Xian Xu reported by E-mail that in the last two weeks he has programmed the basic structure of the multisource display program (see Appendix B). He has also designed the data display program. The program is now capable of the following:

1- Display maps from local files using MapObject. Thus files must be in ESRI format. Currently the program wouldn’t attempt format conversion.
2- Some geo-operations including zoom-in, zoom-out and panning.
3- Map layer control including rename a layer, change layer visibility, change layer order and color, delete a layer, and change layer names.
Chung-Yen Kuo reported by E-mail that: 1- He has found ERS2 tracks in the Bay, and he generated a grid data of (0.0625o*0.0625o) using both the ERS2 and T/P altimetry data (see Appendix C).
2- He compared the OSUMSS95 model and the ERS2 mean sea surface at the ERS2 bin center. Mean for the difference is 0.0281 with std 0.0650 m. This means mean sea surface changes about 3 cm in this area. This value is smaller than our required accuracy (10 cm).
3- He requested tide-gauge data for the station located at the coast in open sea.
4- The G99BM model is still unavailable.
Hari Sugavanam reported by E-mail that:
1- He sent a proposal to Dr. Michael Kobrick for SRTM data in Lake Erie.
2- He downloaded SAR data for Lake Erie that includes the following areas:
latitude:42-41N and longitude:80-81W,
latitude: 42-41N and longitude: 81-82W, and
latitude: 42-41N and longitude: 83-84W
Kevin Cheng reported that he gave Ahmed the GPS instruments to be used in Tampa Bay.
