The GSFC Scanning Mobility Particle Sizer was located at Wallops Island. The following three tables show the dates and times that measurements were taken during the TARFOX Intensive Field Period. Ambient distributions : * DATE Times of operation (UT) 7/16 21:21-24:00 7/17 00:00-13:37 14:16-14:51 15:17-21:23 21:36-24:00 7/18 00:00-04:16 18:21-24:00 7/19 00:00-13:46 17:00-17:50 18:00-22:40 23:16-24:00 7/20 00:00-13:03 13:33-19:33 19:56-24:00 7/21 00:00-11:37 12:08-16:18 16:35-24:00 7/22 00:00-13:46 14:11-18:46 21:11-24:00 7/23 00:00-13:12 14:51-18:46 18:58-19:53 20:04-21:34 22:00-24:00 7/24 00:00-14:16 15:48-17:43 21:23-24:00 7/25 00:00-13:03 13:58-18:38 21:15-24:00 7/26 00:00-15:00 15:31-18:21 * Ambient distributions are in the approximate size range 20 nm to 700 nm. This window may vary a bit, depending on the particular experimental setup being used.
