Issue with MERRA2 data from September 2020 - action is recommended!

Dear windPRO online-data user

NASA has notified us about an issue with the September 2020 release of the MERRA2 data. This data was released from NASA on October 20^th, 2020 and added for distribution in windPRO on October 24^th, 2020.

The MERRA2 science team at NASA does not recommend using these September 2020 data - and is currently reprocessing the data.

MERRA2 data from September 2020 has now been removed from the windPRO online-data services. For users who have downloaded MERRA2 data in the period between October 24^th and November 3^rd, we recommend that you consider taking the following actions with your windPRO project:

• Remove the MERRA2-data for the month of September 2020
• Redo any calculations or reports where you have used these September 2020 records

The actual nature of the issue is unknown to the windPRO online-data team. We will send out a new notification when new MERRA2 data for September 2020 has become available from NASA sources. A little more information is available at the windPRO wiki: here.

Best regards,
The windPRO online data team
