In recent years，As one of the main greenhouse gases，The emissions of methane in the Arctic area have aroused widespread attention。American researchers recently used high Bet365 lotto review -resolution satellite and airborne imaging technology to conduct a study，The actual situation of the actual situation of the actual emission of methane in the Arctic Lake and Wetland provides new insights。Related research recently published on the Earth Physics Research Express，The author is Ethan D. Kyzivat and Brown University Earth、Professor Laurence C. Smith, a professor at the Department of Environment and Planet Sciences。

The Arctic region is significantly higher than the global average due to the heating rate，Become one of the fastest regions in the world。Therefore，The accurate tracking of methane emissions in the region is very important。This new study uses high Bet365 lotto review -resolution satellite and airborne imaging technology provided by the U.S. Aerospace Office，Breaking the difficulties caused by the huge scale and complex natural landforms in the Arctic region，provides more accurate data for the estimation of the methane emissions of the small lake。Research Following the area of ​​about 1/10 square kilometers or smaller lakes，To avoid overly estimating its actual emissions of methane。

This new research results contradict with past research results。Compared to previous research based on low -resolution data sets，New research results show，The number of small lakes that have not been recorded by the map is far less than expected，The proportion of it in overall methane emissions has decreased significantly。Specifically，Some researchers thought it was，The methane emissions of small lakes account for about 40%of the Arctic region，This number is actually only 3%。other，Researchers discovered，Small lakes are larger sources of methane emissions in the unit area。

Kozwit pointed out，Research bet365 live casino games indicates，Although these small lakes only occupy a small landform area，Their emission level is not proportional。Traditionally，How many people do the small lake in the lack of clear understanding of the area，New high -resolution data set helps researchers to make estimates more accurately。Old data，The number of small lakes that can be seen is calculated by statistics，To estimate the total number of small lakes that are not recorded by the area and the amount of methane emission emitted by the area。Researchers' new analysis and display of aerial images，Little lakes that have not been recorded by the map are much less than previously estimated，greatly reduced the estimated value of the total number of methane emissions。The research results provide support for effectively updating the understanding of methane emissions。

This research project was originally aimed at looking for hidden lakes in the Arctic，But with the researchers to check the data more carefully，This plan has changed。This study combines high bet365 best casino games -resolution airborne data with global maps involving lakes involving the Arctic region，Get some unexpected but pleasant discovery。For example，Studies show，Many lakes are still repeatedly calculated as wetland，This repeated calculation increases the estimation of methane emissions in the region。Based on the number of small lakes recorded by the map recognized in this study，Researchers think，The scale of emissions is smaller than previously thought。

Another unexpected discovery of the study involved in the methodology level。In the field of methane modeling，There are two widely accepted estimates。One is an estimate of "bottom -up"，Simulate methane emissions based on the map，As Kozwit and Smith did in this research。Another method is the estimate of "top -down"，Simulate methane emissions based on the results of atmospheric measurement。According to Smith's statement，In the past 10 years，Data produced by two different methods have disturbing differences，New data from this study may help shrink the differences between bet365 best casino games these two methods，to reconcile it。Smith said，"Perhaps 15-20 years of deadlock may already exist，But the conclusion is，High Bet365 lotto review -resolution satellite scheme can now allow researchers who use the "bottom -up" method to better understand how much methane has been discharged。"He also added to say，Now people can actually see the smallest people in these water bodies，Their number is not as rich as it was once calculated。The final result of all this will reduce the estimation value under the "bottom -up" method，Make the results more consistent with the estimation of "top -down"。This will unite these two research communities。Therefore，Researchers hope to use this research work as a concept verification，and expand their methane modeling technology to other parts of the world。

This research not only corrects the error of the previous estimation of the estimation of methane emissions of the Arctic Lake and Wetland，。Due to the improvement of satellite resolution，"Modeling from the bottom up" will be more accurate，It is expected to promote bet365 best casino games two methods to return。Future research can be committed to extending the application of this methane modeling technology to the global scope，To understand the dynamic process of global methane emissions more comprehensive。 (Chu Guofei/Compilation)
