The ORNL DAAC has restored access to the Daymet Version 4 Monthly Latency: Daily Surface Weather Data, as of September 27, 2022. Access to this dataset was restricted on July 28, 2022 due to differences between this product and the standard Daymet: Daily Surface Weather Data on a 1-km Grid for North America, Version 4 data. We have determined that the differences were due to missing daily variable readings used as input in the Daymet V4 processing in the month of January for a significant portion of Canadian weather stations for the years 2020 and 2021. We have determined that the Monthly Latency data were not affected by this issue, and we are updating the standard data products. Please see the news article entitled Daymet V4 Updates Forthcoming for 2000 and 2021 for details.
We apologize for any inconvenience that this issue has caused in your research.
