Air Qual­ity Mon­i­tor­ing

Beijing Review - - THIS WEEK -

China an­nounced on Au­gust 26 the launch of a plan to bet­ter mon­i­tor and con­trol smog in key re­gions through satel­lite re­mote sens­ing.

The Min­istry of Ecol­ogy and En­vi­ron­ment said a grid net­work to mon­i­tor the den­sity of PM 2.5 will grad­u­ally cover Bei­jing, Tian­jin and 26 ci­ties in nearby prov­inces, 11 ci­ties on the Fenhe and Weihe river plains, as well as 41 ci­ties on the Yangtze River Delta.

With tech­nolo­gies in­clud­ing re­mote sens­ing, au­thor­i­ties in the Bei­jing head­quar­ters can dis­cover en­vi­ron­men­tal prob­lems in far­away re­gions quickly and di­rect im­me­di­ate ac­tion, ac­cord­ing to Zhao Qun­y­ing, an of­fi­cial in charge of en­vi­ron­men­tal su­per­vi­sion at the min­istry.

“This can im­prove the ef­fi­ciency of reg­u­la­tion and ad­dress the prob­lem of in­ad­e­quate en­force­ment per­son­nel for the broad re­gions un­der scru­tiny,” Zhao said.

Re­gions cov­ered by the net­work will be di­vided into grid units of 9 square km. The units with rel­a­tively high den­sity of PM 2.5 are listed as key ar­eas to watch.

By Oc­to­ber, Bei­jing, Tian­jin and nearby ci­ties will be in­cluded in the net­work. Ci­ties on the Fenhe and Weihe river plains will be cov­ered start­ing in Oc­to­ber, while those in the Yangtze River Delta will be cov­ered in Fe­bru­ary 2019, ac­cord­ing to Zhao.
