the avhrr pathfinder program
The AVHRR Pathfinder Program
  • Advanced Very High Resolution Radiometer (AVHRR) on NOAA Polar Orbiters
  • Heritage: NOAA/NASA AVHRR Oceans Pathfinder Program of the 1990’s (V4)
  • Collaboration: NODC, NCDC, RSMAS, NASA PO.DAAC

To develop the SST climate data record

for AVHRR in a sustained environment

avhrr pathfinder version 5
AVHRR Pathfinder Version 5
  • Coverage: Global, 1985-near present
  • Spatial resolution: ~ 4 km
  • Averaging periods: Daily, 5-day, 7-day, 8-day, Monthly, and Yearly (day and night)
  • Corresponding climatologies
  • FGDC and Rich Inventory Metadata
  • Satisfies most IOOS DMAC requirements

improvements over pathfinder v4
Improvements over Pathfinder V4
  • Finer global resolution - now 4 km was 9 km
  • Significantly improved land mask
  • Inland waters and lake observations
  • More ancillary and statistical data
  • Longer time series… now in our 21st year!

Climate, coastal,and ecosystemapplications now possible!

improved coastal coverage
Improved Coastal Coverage
  • ReefBase reef location database ~ 8000 sites
  • 9 km Pathfinder coverage only 61%
  • 4 km Pathfinder coverage: > 98%

improvements coming in pfv 6
Improvements Coming in PFV 6
  • Wind and aerosol ancillary data
  • Improved QC including aerosol flagging and better use of sea ice
  • Improved data management (HDF5 with CF and ACDD metadata?)
  • 1985-2005 (maybe back to 1981?)
  • Implement “18-line problem” correction with new global gridding scheme
connections to ghrsst
Connections to GHRSST
  • GODAE High Resolution SST (GHRSST)
  • GHRSST is both real time and retrospective
  • Optimizing the retrospective connection…
    • Level 2
    • Times of Observation
    • All AVHRRs?
    • Error estimates
