Here we present the results of comparison between operational NO2 vertical column data by Global Ozone Monitoring Experiment (GOME) onboard ERS-2 satellite and ground-based measurements at Issyk-Kul station in Kyrgyzstan, northern Tien Shan. The data of GOME, taken for the period of 1996–2002, was found to be reasonably close to the results of ground-based sunrise measurements. The latter were adjusted to the time of GOME overpass nearby noon, providing direct comparison between satellite and ground-based data. According to the results, there is 0.6 × 1015 mol/cm2 (18%) overestimation of NO2 vertical column by GOME, compared to our ground-based data. 相似文献

We consider a method for diagnostics of the engine flow passage technical status of a maneuverable aircraft operating in a
wide range of altitudes and speeds; the behavior of measured parameter deviations from throttle characteristics and calculated
characteristics of the flow passage units from their initial values is used for diagnostics. We present the methods for determining
these deviations as well as flight conditions and engine operation modes at which diagnostics is made possible. 相似文献

We present the regression models for determining the total excess air ratio αΣ and gas temperature T
g
* upstream of the high-pressure turbine formed on the basis of the engine parameter values that are regularly measured. The
sensitivity of the regression models presented to the sensor and instrumentation precision is studied. The errors of measuring
and calculating αΣ and T
g
* in different altitude-speed engine operation conditions are shown. 相似文献
