Transition from METOP-B to METOP-C for the 10 daily EPS Normalized Difference Vegetation Index (NDVI) v2 ENDVI10 Product Generation
Announcing the operational switch from METOP-B to METOP-C ENDVI10 products.
- Dec. 16, 2024
We are transitioning from METOP-B to METOP-C for the ENDVI10 product generation to address the effects of radiometric degradation in METOP-B and ensure data continuity and accuracy. The switch to METOP-C will take effect on the 01/01/2025 data file (to be released on the 12th January 2025). The ENDVI10 product will be reprocessed from 01/01/2023 using METOP-C data, ultimately replacing the currently available data based on METOP-B (replacement wil take place on the 10th January 2025), providing data continuity since degradation began in the summer of 2023. The METOP-B products for 2023 and 2024 will be available on our Data Server for 6 months. For more details, visit https://lsa-saf.eumetsat.int/en/data/products/vegetation/#NDVI.
The sensor platform used is specified in the XML metadata file included with the product, under:
/MD_Metadata/identificationInfo/MD_DataIdentification/aggregationInfo/MD_AggregateInformation/initiativeType/DS_InitiativeTypeCode[@codeListValue="platform"].
Reliable ENDVI10 Production Through METOP-C Transition
- Mitigating METOP-B Degradation:
Over time, METOP-B’s radiometric sensors have shown degradation, affecting data quality. By switching to METOP-C, we restore accuracy and maintain the reliability users depend on for ENDVI10 applications.
- Improved Data Consistency:
Operating METOP-C alongside METOP-A and METOP-B has reduced forecast errors and supported consistent data collection. This ensures better accuracy in predictive modeling and long-term environmental monitoring.
As METOP-B’s radiometric sensors degrade, spatial noise becomes more pronounced in ENDVI10 data, especially in highly vegetated areas, like the Amazon forest. This noise shows up as inconsistent pixel values, particularly visible in areas with high ENDVI10.
