Sensitivity analysis for water vapor profile estimation with Infrared: IR sounder data based on inversion is carried out. Through simulation study, it is found that influence due to ground surface relative humidity estimation error is greater than that of sea surface temperature estimation error on the water vapor vertical profile retrievals.

The compositional profile of graded distributed Bragg reflectors (DBRs) in vertical-cavity surface-emitting lasers (VCSELs) is investigated. Molecular flux measurements allow to determine small differences between the nominal profile and the epitaxially grown structures. These small differences explain completely the suppression of the higher-order satellites in the HRXRD (high-resolution x-ray...

Vertical electron density profile is an important source of information on the Earth’s ionosphere. It is well known that such vertical electron density profile can be retrieved using LEO (Low Earth Orbit) satellite RO (radio occultation) data. With more and more LEO satellite data available (such as CHAMP, SAC_C, GRACE, COSMIC), the retrieved vertical electron density can be more accurate if so...
