ABSTRACT: French records of grape-harvest dates in Burgundy were used to reconstruct spring-summer temperatures from 1370 to 2003 using a process-based phenology model developed for the Pinot Noir grape. Our results reveal that temperatures as high as those reached in the 1990s have occurred several times in Burgundy since 1370. However, the summer of 2003 appears to have been extraordinary, with temperatures that were probably higher than in any other year since 1370. ADDITIONAL REFERENCE: Le Roy Ladurie, E.

PERIOD OF RECORD: 1370 - 2003 AD DESCRIPTION: Pinot Noir grape harvest dates for Burgundy, France, and April-August Temperature Reconstruction. The grape harvest date series is a corrected and updated harvest date series from Le Roy Ladurie (1983) covering 1370 to 1977 and completed until 2003 for the Burgundy region. Grape harvest dates were collected from up to 18 cities or villages in Burgundy (the actual number depends on the year) since 1370. To avoid possible biases due to the variability of data availability each year, Dijon - the longest series overall and the only one available for some periods - was chosen as the reference series. However, the 17 other series
