Products

The primary products to be derived from the IASI-NG mission include (in descending order of priority):

1. Temperature profile
2. Water vapour profile
3. Sea surface temperature
4. Land surface temperature
5. Cloud cover
6. Cloud top height
7. Cloud top temperature
8. Outgoing spectral radiance at the top of the atmosphere
9. Surface emissivity in window channels
10. O₃ profile
11. O₃ total column
12. ¹ CO total column and profile
13. Volcanic SO₂ total column
14. CH₄ total column
15. NH₃ total column
16. HNO₃ total column
17. CO₂ total column
18. N₂O total column

¹ When there is a thermal contrast, IASI-NG has low sensitivity to trace gases near the surface. In this situation the accuracy of some products (O₃, SO₂, CO and CH₄) can be improved by the addition of data from the UVNS.

Further products to which IASI-NG contributes:

19. Depth of the planetary boundary layer
20. Tropopause height
21. Downwelling longwave spectral irradiance at the surface
22. CH₃OH
23. HCOOH
24. PAN
