Abstract

The problem of estimation of average fields of air pollutant concentration based on local measurement data is stated: the problem of the passive location of the atmosphere by wind, or the problem of the fluid location of the atmosphere. The definitions of new functions are given: the average effective field of concentration and the average effective field of sources. The system of integral equations these functions obey is also presented. The results of numerical estimates of quasi-two-dimensional average fields of methane concentration in the area of the Barents and Kara seas retrieved from data on surface concentrations measured on Belyi Island in the summer of 2016 and 2017 are analyzed. A typical feature of the resulting fields is their mosaic pattern, as well as the higher values of methane concentration on the continent and in the coastal zone.

2016-2017年夏季巴伦支和卡拉海地区甲烷浓度的空间分布估算

摘要

提出了基于局部测量数据估算空气污染物浓度的平均场的问题：通过风使大气被动定位的问题，或大气的流体定位问题。给出了新功能的定义：浓度的平均有效范围和源的平均有效范围。还介绍了这些函数服从的积分方程组。从2016年和2017年夏季在Belyi岛测得的地表浓度数据中获得的巴伦支和卡拉海地区甲烷浓度的准二维平均场的数值估计结果进行了分析。结果字段的典型特征是它们的马赛克图案，
