\*DisALEXI is only available back to 2001 due to model design and input limitations.&#x20;

For retrieval of large volumes of data, users are encouraged to retrieve OpenET data directly from the OpenET data archives in the [Google Earth Public Data Catalog](https://developers.google.com/earth-engine/datasets). Data will be periodically added so check back often.

The following dataset are available from **2000**-**2024 on Google Earth Engine**:

* [Ensemble Monthly ET](https://developers.google.com/earth-engine/datasets/catalog/OpenET_ENSEMBLE_CONUS_GRIDMET_MONTHLY_v2_0)
* [eeMETRIC Monthly ET](https://developers.google.com/earth-engine/datasets/catalog/OpenET_EEMETRIC_CONUS_GRIDMET_MONTHLY_v2_0)
* [SIMS Monthly ET](https://developers.google.com/earth-engine/datasets/catalog/OpenET_SIMS_CONUS_GRIDMET_MONTHLY_v2_0)
* [PT-JPL Monthly ET](https://developers.google.com/earth-engine/datasets/catalog/OpenET_PTJPL_CONUS_GRIDMET_MONTHLY_v2_0)
* [SSEBop Monthly ET](https://developers.google.com/earth-engine/datasets/catalog/OpenET_SSEBOP_CONUS_GRIDMET_MONTHLY_v2_0)
* [DisALEXI Monthly ET ](https://developers.google.com/earth-engine/datasets/catalog/OpenET_DISALEXI_CONUS_GRIDMET_MONTHLY_v2_0)\*
* [geeSEBAL Monthly ET ](https://developers.google.com/earth-engine/datasets/catalog/OpenET_GEESEBAL_CONUS_GRIDMET_MONTHLY_v2_0)

Users may register their Google Earth Engine account using their Cloud Project ID in their OpenET [profile](https://account.etdata.org/settings/profile). Linking a user’s Cloud Project ID to their OpenET account will increase quota limits.&#x20;

Users may still need to break larger queries into smaller units (in terms of spatial area or time period) to avoid memory timeout errors on Earth Engine.
