APPENDIX

EXPLANATORY NOTES

1.	Opening of the meeting

2.	Election of Chairman

3.	Adoption of working arrangements

4.	Adoption of the agenda

Self explanatory

5.	Aerodrome observation requirements

5.1.	Reporting requirements and criteria

The group is expected to re-address the issue of the reported elements under "present weather" and "recent weather", building upon the initial discussions at the AMOSSG/2 Meeting. To be able to progress this sub-task, study notes containing specific proposals from members would be essential. In addition the task of providing a precise definition of "vicinity" was re-assigned to the group following the MET Divisional Meeting (2002) (Rec, 2/3 refers) along with consideration of the need to harmonize the criteria for the issuance of SPECI with those for including change groups within a TAF.

5.2.	Use of automated equipment during operational hours

Following the inclusion of provisions for the use of fully automated observations during no- operational hours in draft Amendment 73 to Annex 3 the group is expected to study the possibility of such observations being used during operational hours. The group is invited to submit study notes identifying any potential difficulties and solutions thereto.

5.3.	Use of remote sensing techniques

A report is expected from Michel on the use of remote sensing observing techniques. The group is expected to develop proposals for an amendment to Annex 3 or guidance material, as necessary.

6.	Capability of automatic observing equipment to meet aeronautical requirements

Reports are expected regarding progress made in the automatic detection of cloud types, together with an up-to-date assessment of the capability of automated systems to meet the expected future requirements.

7.	Aerodrome forecast requirements

The group is expected to study the need for a greater accuracy in the first 3 hours of a TAF and to update the general requirements for the accuracy of forecasts, currently provided in Attachment E to Annex 3 based on a report from IATA.

8.	Guidance material

The group is expected to review a first draft of a manual on the use of automated observing equipment at aerodromes which has been developed by Michel.

9.	Future work programme

The future work programme of the group will be discussed based on the updated programme agreed by correspondence following the MET Divisional Meeting (2002). Necessary updates will be introduced depending on the outcome of the meeting.

10.	Any other business

11.	Closure of the meeting

Self explanatory.
