16 The Past, Present, and Future of the AVHRR Pathfinder SST Program

Fig. 16.1 Excerpt from a 22 February 1991 email to Peter Cornillon, demonstrating the slow data
transmission rates available at the time. Despite the sender’s concerns, the transmission was not
garbled
users of earlier versions of the Pathfinder SST data who had grown accustomed to
accessing it from the PO.DAAC systems. From 2007 to 2009, the NOAA Scientific
Data Stewardship Program supported efforts to transition the reprocessing from the
University of Miami to NODC, where it could be supported over the long term.
Beginning in 2009, new NASA funding augmented the continued NOAA support, with the goal of adding two new components to the Pathfinder SST Program.
The first addition was the ability to generate error estimates, a critical component
necessary to make the future Pathfinder Version 6 data compliant with the standards of the Group for High Resolution SST (GHRSST, Donlon et al., 2007). The
second addition was to enable Pathfinder reprocessing of not just AVHRR GAC
data, but also a large collection of 1 km resolution Local Area Coverage (LAC) and
High Resolution Picture Transmission (HRPT) data from the AVHRR instruments.
By the end of 2010, the GAC reprocessing system is expected to be functional at
NODC and the LAC/HRPT at the University of Rhode Island. Long-term stewardship, archiving, and provision of the Version 6 data to users will take place at
NODC.
