http://wind.nrel.gov/MetData/ A news feed to keep users up-to-date with what's going on at NREL's National Wind Technology Center Friday, 22 November 2013 11:30:00 +0700 http://wind.nrel.gov/MetData/ After failures of both the M4 and M5 data acquisition systems (DAS), both DAS have been reinstalled and all software has been updated. We've also implemented some changes to the data acquisition and processing software. Overall we expect much more stable systems and much higher data availability.

The data acqusition system will be updated soon with the new calibration coefficients. The system will only restart when all of the setting have ben updated. The total duration of the outage is expected to be 08:00 on 8/26/2013 through 17:00 on 8/30/2013.
