Measuring temperature and water vapor profiles with high accuracy and vertical resolution in the upper troposphere and lower stratosphere (UTLS, 5—35 km in height) is significant for improved monitoring of condition changes in the free atmosphere, and simultaneously measuring with laser occultation method is a significant supplement to the existing exploration technology. Here we introduce an algorithm to retrieve temperature and water vapor profiles from laser occultation data, and thoroughly describe the temperature retrieval method from dual oxygen absorption wavelength laser occultation data.In this paper, the method of laser occultation cooperative measuring and retrieval of temperature and water vapor molecular number density is studied and the emphasis is on the method of deriving temperature from detected data. The method is selecting two characteristic absorption peaks corresponding to different transition energy levels from the near-infrared band oxygen absorption spectrum, choosing one absorption line near each absorption peak, using the double absorption wavelength laser corresponding to the two absorption lines and the wavelength laser corresponding to the reference line for occultation measuring.The algorithm steps of cooperative retrieval of temperature and water vapor are retrieving temperature profile from occultation data and deriving pressure profile from temperature profile and the pressure prior value at the reference height of 5 km, then as a second step, retrieving water vapor molecular number density from single water vapor absorption wavelength and reference wavelength laser occultation data.We furthermore simulate the occultation process with selected oxygen absorption wavelength and water vapor absorption wavelength laser signals, and retrieve from the simulated transmittance data. The error term and its transfer relationship in the retrieval process are analyzed and the influence of each error term is presented by the simulation results. This results show that the temperature retrieval errors are generally smaller than 1.05 K, and the water vapor molecular number density retrieval errors are generally smaller 4%, which shows the feasibility of the temperature and water vapor collaborative retrieval method.
