Asunto: [World Magnetic Model] Likely disruption to NOAA Geomagnetic calculator services
Dear NOAA Geomag users,
This is a message from NOAA's National Centers for Environmental Information (formerly National Geophysical Data Center). You received this email because you opted for notifications related to NOAA Geomagnetic models or services. We would like to bring to your attention that, in the event of a U.S. Government shutdown, NOAA Geomagnetic calculators, Application Programming Interface (API) services and our web pages will likely go offline starting 2018-12-22. There are two options for you to obtain magnetic field values during the unavailability of our online calculators.
1) Desktop users may download WMM, IGRF or EMM standalone software from our webpage prior to the shutdown and mobile users may install CrowdMag app from Apple app store or Google play store.
2) Backup calculators and model will be available through the University of Colorado CIRES Geomagnetism site. URL https://geomag.colorado.edu/online-calculators#backup_calculators.
If you need assistance during the shutdown period, please send an email to CIRES Geomagnetism experts at ciresgeomag@colorado.edu or visit https://geomag.colorado.edu/about-us.html.

Asunto: [World Magnetic Model] WMM2015 degraded performance warning -- March 2018
Dear World Magnetic Model users,
This is a message from NOAA's National Centers for Environmental Information (formerly National Geophysical Data Center).
We would like to bring to your attention that WMM Gridded Variation (GV) error has recently exceeded the WMM performance specification in the Arctic region. Other geographic areas and other model parameters are not affected. This performance degradation is caused by fast-changing core flows in the North polar region of the Earth’s outer core. We invite your feedback on potential impacts and whether an out-of-cycle WMM update would benefit your operations.
More details in the attached white paper. Additional information is available from WMM website. Questions and comments may be addressed to geomag.models@noaa.gov
