The altimeter measurement is affected by different errors as illustrated by the following figure and discussed in Escudier et al. (2017):
|
Along-track measurements (Level 3) – main sources of errors
- Main sources of errors
- Instrumental errors
- Environmental & sea state errors
- Geophysical errors
- Altimeter measurement noises and altimeter along-track observability
- DT vs NRT DUACS products
|
Merged product (Level 4) – main sources of errors
- The main sources of errors
- Quality of the global gridded products
- Quality of the regional gridded products
- DT vs NRT DUACS products
