Data set correction: Global Lake and River Ice Phenology Database

NOAA@NSIDC would like to make users aware that the ice-off dates for certain years between 2006-2019 for 20 Maine Lakes in this database have been corrected. The source of these dates for 2007-2008 onwards for 19 of these lakes are the Maine Department of Agriculture, Conservation and Forestry (DACF). For China Lake, all the data are from the Townline/China Lake Association. Discrepancies in the ice-off dates of one day early were discovered, which were either due to a miscalculation of the Julian day or typographical errors. These have now been corrected so that the ice-off dates in the database match those reported by Maine DACF or the Townline/China Lake Association. Also, new ice-off dates for the 2014-2015 season for Pennessewassee (Norway) Lake, Eagle Lake, and China Lake were added.

Access to the data and documentation is provided on the data set web page at NSIDC:
