This dataset focuses on large methane (CH4) emissions from Landfills in the Stockton, CA and Dallas, TX regions. For more information on EMIT please visit NASA's [Land Processing Distributed Active Archive Center](https://lpdaac.usgs.gov/data/get-started-data/collection-overview/missions/emit-overview/#emit-metadata) (LP DAAC) and the EMIT Dataset Overview page on the U.S. [Greenhouse Gas Center](https://earth.gov/ghgcenter/data-catalog/emit-ch4plume-v1). | ||
|
||
- **Temporal Extent:** June 22, and August 25, 2023 | ||
- **Temporal Resolution:** Variable (based on ISS orbit, solar illumination, and target mask) | ||
- **Spatial Extent:** Stockton, CA and Dallas, TX | ||
- **Spatial Resolution:** 60 m | ||
- **Data Units:** Parts per million-meter (ppm m) | ||
- **Data Type:** Research | ||

## Disclaimer | ||
Uncertainty in the methane (ppm-m) depends on instrument, observation, and surface factors as described in the [ATBD](https://lpdaac.usgs.gov/documents/1696/EMIT_GHG_ATBD_V1.pdf) by Broderick, et al. 2023. An uncertainty value (ppm-m) is calculated and reported for each plume complex. As described in the ATBD, EMIT plume complexes are manually identified and reviewed. While we publish high confidence examples, false positives can occur and when identified these cases are removed from subsequent data releases. | ||
