The daily and monthly low latency datasets listed indicate the data delivered more frequently throughout the year using estimated carbon dioxide input data. Once the carbon dioxide input data has been finalized, the daily and monthly products are permanently published to the high latency collections.

## Version History
The current dataset version is LPJ-EOSIM v1, which replaced LPJ-wsl v1 in the US GHG Center in April 2024. Summary of version update changes:
- Model updates and improvements, including improved data latency with more regular updates and driver-specific model recalibration
- Addition of two new data layers: LPJ-EOSIM model estimated wetland methane emissions using ERA5 climate input forcing data, and using the mean of both MERRA-2 and ERA5 climate input forcing data (mean ensemble). For the daily data layer, the LPJ-wsl dataset only provided LPJ-EOSIM estimates using MERRA-2 climate input forcing data until the end of 2021.
- Addition of two new data layers: LPJ-EOSIM model estimated wetland methane emissions using ERA5 climate input forcing data, and using the mean of both MERRA-2 and ERA5 climate input forcing data (mean ensemble). The LPJ-wsl dataset only provided estimates using MERRA-2 climate input forcing data until the end of 2021.
- LPJ-EOSIM data is obtained directly from the LP DAAC in Cloud Optimized GeoTIFF (COG) format (LPJ-wsl data was in NetCDF format and transformed to COG)
- LPJ-wsl data remains accessible from the [GMAO website](https://gmao.gsfc.nasa.gov/gmaoftp/lott/CH4/wetlands/)
- In October 2024, the version of the dataset in the GHG Center was changed from LPJ-EOSIM v2 to LPJ-EOSIM v1 to match the version of the source dataset in the NASA EOSDIS Land Processes Distributed Active Archive Center (LP DAAC). This was a correction of the version number only, and does not represent any changes to the underlying data.
