Thats the first problem should be solved for getting a good retrieval. Based on the cognition, a method is developed to assess the retrievability of temperature and the distribution of the global retrievability with HIRS/3 and AIRS data in Jan and Jul are firstly given by using the NCEP reanalysis data. The results show that the retrievability of temperature is low in the upper and lower atmosphere, and high between 400 hPa and 850 hPa.

The results show that the retrievability of temperature is low in the upper and lower atmosphere, and high between 400 hPa and 850 hPa. In geographical distribution, the retrievabilities are low in the low latitude marine regions and in some regions in Antarctica, and relatively high in mid-high latitude regions and continental regions.

Being combining with products distribution in styrene oxidation, we propose the styrene epoxidation carry out with Ti metallacyclo intermediates, And at the same time Ti-ZSM-5 have properties both catalytic epoxidation and acid-catalysis, namely the skeletal Ti can catalyze styrene epoxidation to styrene oxide and the skeletal Ti and Al can provide Lewis acid site to cause the rearrangement of styrene oxide to phenylacetaldehyde rapidly, the solvolysis to glycols and the cleavage of C=C double bond. Ti-ZSM-5 can also provide Bronsted acid site simultaneously, which is also catalytic center for the solvolysis to glycols.
