EMIT Filenames
EMIT filenames (i.e., the local granule ID) follow a naming convention which gives useful information regarding the specific product.
Level 1 and 2 data product filenames will adhere to the following naming convention: EMIT_L1B_RAD_001_20220101T083015_2200105_007
- EMIT – Sensor
- L1B – Product Level
- RAD – Product Type
- 001 – Product Version Number
- 20220101 – Date of Acquisition (YYYYMMDD)
- T083015 – Time of Acquisition (HHMMSS) (in UTC)
- 2200105 – Orbit identification number (YYDOYNN), where NN is a two-digit incrementing orbit number for each day
- 007 – Scene identification number
Level 2B Estimated Methane Plume Complexes cloud optimized GeoTIFF filenames adhere to the following naming convention: EMIT_L2B_CH4PLM_001_20220101T083015_000120
- EMIT – Sensor
- L2B – Product Level
- CH4PLM – Product Type
- 001 – Product Version Number
- 20220101 – Date of Acquisition (YYYYMMDD)
- T083015 – Time of Acquisition (HHMMSS) (in UTC)
- 000120 – Unique global plume complex identifier
For level 3 and 4 data products, filenames will follow the naming convention: EMIT_L3_ASA_001
- EMIT – Sensor
- L3 – Product Level
- ASA – Product Type
- 001 – Product Version Number
Each EMIT product may contain multiple NetCDF files and one quick look PNG file. The PNG file name will match the main product of the collection but will have PNG as the data format. For example, the EMITL1BRAD data product contains two separate NetCDF files: radiance (EMIT_L1B_RAD_001_20220101T083015_2200105_007.nc) and observation (EMIT_L1B_OBS_001_20220101T083015_2200105_007.nc). The browse file will be EMIT_L1B_RAD_001_20220101T083015_2200105_007.png.
EMIT Product Long Name
The EMIT Product Long Name (i.e., Collection-Level) naming convention provides useful information regarding all EMIT swath products.
Below is an example for an EMIT Level 1B product, although all EMIT Product Long Names follow the same structure.
The EMIT L1B At-Sensor Calibrated Radiance and Geolocation Data 60 m V001 collection has the following characteristics:
- EMIT – Instrument
- L1B – Processing Level
- At-Sensor Calibrated Radiance and Geolocation Data – Geophysical Parameter
- 60 m – Spatial Resolution
- V001 – Version Number
