摘要

通过在北极徒步旅行来确定甲烷异常导致温度升高需要大量的人力劳动。根据初步预测,到2100年,北极的永久冻土将大大恶化,这将产生许多后果。事实上,在100米以上的永久冻土层中,释放不到0.1%的有机碳(大约10000 ppm的СН4形式的碳)可以使大气中的甲烷浓度增加一倍,而甲烷是比二氧化碳强20倍的温室气体。有必要制造一个拉曼激光雷达来监测永久冻土中甲烷水合物的排放。

Lidar for monitoring methane emission in Siberian permafrost
Identifying methane anomalies responsible for the temperature increase, by hiking trails in the Arctic requires great human labor .According to the tentative forecast by the year 2100 Arctic permafrost will greatly deteriorate, which will have numerous consequences. Indeed, release of less than 0.1% of the organic carbon stored in the upper 100-meter permafrost level (approximately 10000 ppm of carbon in the СН4 form) can double concentration of atmospheric methane, which is roughly 20 times more potent greenhouse gas than the CO2. Necessary to create a Raman lidar for monitoring of emissions of methane hydrate from the permafrost.
