MSU / amsu Microwave light temperature for ocean air tempera-ture: Discussion on applicability of climate change research

Abstract

using NASA satellite applications and Research laboratory ( the Center for satellite Applications and Do , STAR ) provide msu/amsu satellite Microwave light temperature data V3.0 version , combines three sets of profiling data datasets , through different heights over the ocean ? , Applicability analysis for different areas and seasons , to explore msu/amsu Characteristics of temperature variation in the upper atmosphere of tropical marine area , and to reveal the response of the light temperature data to the ocean by synthetic analysis , To Explore msu/amsu Applicability and science of data in tropical marine areas sex . results show :(1 msu/amsu Light temperature data in ° ° E~70 °W , | °S ~15 ° N The range of tropical marine areas is more adaptable ; ( 2 Hot with ocean area troposphere upper and middle atmosphere both warming trend , Change rate is 0.045 K/(Ten a ) + 0.107 K /(Ten a ), warming mutation now Like a 1980 end of Year one 1990 age , stratospheric lower atmosphere cooling trend , The rate of change is -0.345 K /( a), Cooling Mutation appear in 1990 mid-term ;(3) in tropical Ocean area , High altitude atmospheric temperature trends have strong regional characteristics , relative to Middle East too Ping Yang , Indian Ocean - Increase in the western Pacific region , cool trend changes more significantly . The temperature increase in the troposphere decreases with height. . ping ( ) cooling trends at lower levels of the flow layer are not changed in the seasons , and the troposphere is the autumn , The winter warming trend is significantly greater than the spring , Summer , warming in winter especially to obvious ;( 4 msu/amsu Bright temperature data have a good response to tropical oceanic temperature anomalies , to make up for the scarcity of observational data in the ocean area case , better monitor ocean area .
