环境卫星上的三个大气物理学仪器GOMOS、MIPAS和SCIAMACHY对臭氧和温度的测量正在与比利时皇家气象研究所的Brewer 16分光光度计和臭氧和无线电探测进行比较。关于SCIAMACHY臭氧总量值，与我们的Brewer测量值相比，存在约-5%的负偏差。没有可能研究云层或太阳天顶角的影响。示出了从我们的站的SCIAMACHY像素的距离的重要性。GOMOS的臭氧廓线与我们的臭氧探测进行了比较，但由于GOMOS在白天测量的廓线质量较差，因此比较是以定性的方式进行的。对于温度测量，使用无线电探空仪可以获得更多的同地数据。GOMOS的低分辨率温度廓线与无线电探空仪的廓线相比非常好。然而，从数据中并不清楚哪些数值是实际检索的，哪些数值是从气候学中得出的。的MIPAS温度测量已被分析为距离，压力水平和测量时间的函数。与无线电探空资料的符合率一般在2%以内。当使用夜间数据时，存在对高度的依赖性的指示，当较大的数据集变得可用时，必须确认夜间数据。
The ozone and temperature measurements by the three atmospheric physics instruments GOMOS, MIPAS and SCIAMACHY aboard the ENVISAT satellite are being compared with the measurements performed with the Brewer 16 spectrophotometer and the ozone- and radiosoundings at the Royal Meteorological Institute of Belgium. Regarding the SCIAMACHY total ozone values, there is a negative bias of about -5% compared to our Brewer measurements. There was no possibility to study the influence of clouds or solar zenith angle. The importance of the distance of the SCIAMACHY pixel from our stations is shown. The GOMOS ozone profiles have been compared to our ozone soundings, but due to the poor quality of the GOMOS profiles measured during daytime, the comparison is made in a qualitative way. For the temperature measurements, there was more co-located data available using radiosondes. The GOMOS low resolution temperature profiles compare very well with the radiosonde profiles. However, from the data it was not clear which values were actually retrieved and which values were taken from a climatology. The MIPAS temperature measurements have been analyzed as a function of distance, pressure level and time of measurement. The general agreement with the radiosonde data is within 2%. There is an indication of a dependency on the altitude when using nighttime data which has to be confirmed when a larger dataset becomes available.
