1 Storm tracking and scan scheduling

2 Processing tree (in minutes) 05:00 Nimrod rainfall data produced 10:00 Nimrod data from BADC now at Chilbolton 10:30 Nimrod data cut to size on 400x400km grid 0:00 Met Office Radar network Volume scan 11:00 Tracking done. File with storm props and labels produced. 11:30 New scan procedure submitted to Chilbolton radar

3 Scan Scheduling

4 Prioritize storms that are already being tracked

5 Scan Scheduling Prioritize storms that are already being tracked

6 Scan Scheduling Issue when storms cross 0 azimuth line Prioritize storms that are already being tracked

7 Scan Scheduling Issue when storms cross 0 azimuth line Prioritize storms that are already being tracked

8 Scan Scheduling Issue when storms cross 0 azimuth line Prioritize storms that are already being tracked

9 Scan Scheduling Issue when storms cross 0 azimuth line Prioritize storms that are already being tracked

10 Scan Scheduling Issue when storms cross 0 azimuth line Prioritize storms that are already being tracked

11 Scan Scheduling Issue when storms cross 0 azimuth line Prioritize storms that are already being tracked

12 64 Pulse pairs per ray Scan at 1deg/second 32 Pulse pairs per ray Scan at 2deg/second Rays are equal width (azimuth) 32 Pulse pairs = less data per ray (more noise?) 2deg/second = faster scanning Scan Options

13 64 Pulse pairs per ray Scan at 0.2deg/second 32 Pulse pairs per ray Scan at 0.2deg/second Scan Options

14 Further work Automate process – John Nicol’s code waits for new Nimrod file to arrive at Chilbolton, then cuts it to size – Add “wait” command to tracking code that looks at list of filenames and waits for new Nimrod files to process – Link tracking and scan scheduler Test code at Chilbolton Test remote scanning display
