iQuam upgrade to v2.1 and status of NOAA SST monitoring system

17 March 2020 Published by

Dear GHRSST Colleagues,

You may have noticed that the NOAA Monitoring systems iQuam, SQUAM, and ARMS, have been down, or experienced significant anomalies, in the past several weeks. This is due to a combination of several factors, the two major ones being widespread IT outages of the NOAA STAR web server, and of the SST processing cluster (which “very fortuitously” coincided in time). The COVID-19 virus didn’t help, either. We are working to recover, but it will take some time. Your understanding and patience are appreciated.

The iQuam system turned out more robust than the other NOAA SST validation and monitoring sub-systems, and is now up and running. We recommend using the more complete and improved iQuam v2.10 available at The outdated iQuam v2.0 (which currently continues to be reported in the main iQuam url will be retired on 15 April 2020 and discontinued. The superior v2.10 (currently found in a temporary url will be promoted to the prime iQuam url. The http data link will become The ftp for v2.10 will remain

Please consider transitioning to iQuam v2.10, if you haven’t done so yet, at your earliest convenience. Consult the “About” tab in the “iQuam2” url, if you are interested in knowing what’s new in 2.10 compared to 2.0. Send any email queries to (technical questions) and to (science/management). This is a long overdue transition and we appreciate it if you please bear with us.

Many thanks to all our loyal customers and users. NOAA is determined to deliver you a high quality, comprehensive in situ SST for the satellite era, for use in satellite Cal/Val, data assimilation, and other related applications.
