OpenET uses a multi-tiered system for data access.


Quota restrictions exist to ensure the availability of computing resources for the entire OpenET community. Attempting to circumvent quota restrictions through the use of multiple OpenET accounts is a violation of the Terms of Service and will lead to accounts being removed.

Available Tiers

Account quotas will reset at the 1st of every month to the values shown below. When you have your Earth Engine account linked with OpenET the export EECU seconds limit will be set to . This will automatically grant you access to the 2nd tier listed when you add your Cloud Project ID in your OpenET account profile.
