The site ancillary data file that is available for download in MATLAB format under the "Data Download" tab was not being updated at the same frequency as the ancillary data reports on the fluxdata site. We have now corrected that oversight and the site ancillary data file in MATLAB format available for download is up-to-date. Please download a new file to see the latest data. (keep in mind, this file contains only a subset of the ancillary data). The rest of the ancillary data can be downloaded via the data browsing page.
