From the GNSS signal delay we can estimate slant total electron content (STEC), which is defined as ‘integrated’ electron density along the line of sight from Swarm to GNSS satellites. spase://CNES/Person/CDPP-AMDA/R.Haagmans ProjectScientist TEC dataset description https://earth.esa.int/web/guest/document-library/browse-document-library/-/article/swarm-level-2-tec-product-description spase://SMWG/Repository/CDPP/AMDA Online Open CDPP/AMDA HAPI Server https://amda.irap.omp.eu/service/hapi swarmb-gps-all Web Service to this product using the HAPI interface.

The recommendation is given since the uncertainty of the mapping function increases with decreasing elevation angle.
