Inner Shelf DRI Monthly Meeting 2017-07-12

Inner Shelf DRI Monthly Meeting 2017-07-12

attendees: Chris Chickadel, Joe Calantoni, Nirni Kumar, David Honegger, Kevin Haas, Roland Romeiser, André Palóczy, Tom Cook, Falk Feddersen, Matt Spydell, Jim Lerczak, Reg Beach

Agenda:

  • Satellite updates
  • Funding notes from Reggie
  • VTC frequency increase?

Satellite:

  • imagery 2015 pilot data online, request access via email to Roland
  • GeoTiff format, not full quality, high quality data exists
  • Sept/Oct overpass are now included in the online calendar (PSIEX), overpass times (local) are included for four different SVs
  • 87 overpasses possible predicted, not all will be purchased, some are free
  • need input on which ones to order in advance, early Aug – might be able to request as little as 1 week ahead (maybe)
  • Sentinel 1 – acquired automatically (routine) New wave measurement technique using SAR “spotlight” data under investigation ScanSAR imagery ahead of the experiment for planning? Aircraft coordination w/ overpasses

Other:

  • Talk with Reggie about any funding issues, money is out
  • Permitting is in process with CA State, NOAA
  • SAR questions – connect with Reggie
  • Additional VTCs? ship ops / VTC at end of July?, biweekly VTC after?
  • Earliest deployments end of Aug for Jamie and Falk, radars are in on Sept 1 or so
  • Surface wind observation from VAFB are available for 2015 pilot (Jim Doyle contact)
  • Surface winds will be collected by VAFB during main experiment

Thermal IR visualized flow

The attached video shows a 17 minute series of 10 second averaged images from the thermal IR cameras on the APLUW/OSU tower.  Brighter shades indicate relatively warmer temperatures.  The high tide was approximately 2 hours prior to the movie.  Note the strong northward flow which bends into the inlet and intersects a cooler front in the main channel.

APL-UW thermal IR imagery of the New River inlet plume

The imagery above is a preliminary mosaic of the New River inlet plume on May 2, at about 1150 EDT (the companion data to Gordon Farquaharson’s microASAR data in his May 4 post).  Brightness in the image indicates relatively warmer temperatures, and I’ve adjusted the contrast to highlight the plume, making the warmer land white. The plume on this day (due to wind) was shooting north and the plume front(s!) are complicated – including prominent transverse features at N = 3822.5km, E = 286 to 288km. Note there are still kinks in the mapping, so image overlap is not exact, and the camera drift and angular emissivity effects have not been corrected.
