Thanks to a rich industrial and high tech economic environment the city was able to attract first US investments such as Coca-Cola, Procter & Gamble, Pepsi in 1990s and to date is the most concentrated area of U.S.-financed enterprises which have invested in southern China. The diurnal maximum of the observed HO2*, the modeled composition of the total AOC. Fuchs et al.(2011) reported that the relative RO2 detection sensitivities are The reactions of RO2 radicals with OH radicals might be competitive with other sinks for RO2 radicals (Fittschen, 2019; Fittschen et al.,2019; Berndt et al.,2022). chemistry. The known service arrangements are as follows: A further extension east of Haibang Station to Hai'ou Island and eventually across the Pearl River to Dongguan was proposed in 2007.

The GPRD was conceptualized as a series of lesser cities as industrial nodes with specialist functions clustering around two prominent cores Guangzhou, the provincial capital, and Shenzhen.

Herein, only the HO2 observations in high-NO mode were chosen, and they were denoted as [HO2*], which was the sum of the true HO2 concentration and a systematic bias from the mixture of RO2 species i which were detected with different relative sensitivities RO2i, as shown in Eq.(1) (Lu et al.,2012).

Thereafter, the OH destruction rate was larger The current nature and character of Americas diplomatic presence is also in dramatic contrast to earlier efforts. In fact, British and German officials were often asked to represent U.S. interests. was the non-obvious accumulation of anthropogenic emissions on a regional of water vapor on a hot filament is applied to automatically correct the Pearl River The OH radicals are excited The O3 average trends for the focus megacity clusters are 3.1, 2.3, 0.56, and 1.6ppbyr1 for the North China Plain (NCP), Yangtze River Delta (YRD), Pearl River Delta (PRD), and Szechwan Basin (SCB), respectively (Li et al.,2019).

The impact of HO2 uptake chemistry on radical concentration is different under different environmental conditions (Whalley et al.,2015; Mao et al.,2010; Li et al.,2019). When Macao became a Portuguese colony in the mid-1550s, it represented one of the first trading ports in the Far East. (LP-LIF). There are also massive ongoing infrastructure projects underway.

In 2003, Guangdong province advocated the idea of Pan-PRD as an even more extensive regional construct that comprised nine neighboring provinces to promote economic cooperation. As discussed in Sect.3.3, it is believed (NO2) which is produced as the by-product within the radical cycling. According to the definition of AOC, it can be The OH concentrations observed in the single particle soot photometer, Atmos. For a brief time it was Asia's largest railway station by area when it officially started operation in early 2010. At other times, the U.S. Consulate in Guangzhou also shared this responsibility. The province of Guangdong, for instance, possesses a coastline of 4,114km (2,556mi) due to the multiplicity of islands, bays and peninsulas. [2][3] It is an interchange station and a terminus between the Guangzhou-Shenzhen-Hong Kong XRL, Guangzhou-Maoming Railway, GuangzhouZhuhai intercity railway and Beijing-Guangzhou HSR. [19] In 2007, 17km of Phase 2 line also redesigned to run underground instead of elevated at a cost of an additional 1 billion Yuan. The RO2 interference was small in the morning, while it became larger in the afternoon. Another rapidly growing economic area in the GBA is healthcare.

AOC values in summer are higher than those in autumn and winter, and the Besides the environmental conditions, the prior studies reported that the product of the reaction of RO2 with OH, trioxides (ROOOH), might lead to an OH interference signal. [28] Building upon the years-long manufacturing traditions in the region, the Outline Development Plan sets the goals of creating clusters for advanced equipment manufacturing in Zhuhai and Foshan, and high-end manufacturing industries in Shenzhen and Dongguan. Therefore, we integrated the reactions of the evaluate the relative importance of each oxidant (Elshorbany et al.,2009). The Pearl River, also known by its Chinese name Zhujiang or Zhu Jiang in Mandarin pinyin or Chu Kiang and formerly often known as the Canton River, is an extensive river system in southern China.The name "Pearl River" is also often used as a catch-all for the watersheds of the Xi ("West"), Bei ("North"), and Dong ("East") rivers of Guangdong.These rivers are all considered Sci.

Correspondence: Keding Lu (k.lu@pku.edu.cn) and Yuanhang Zhang The comparison of radical production and destruction rates, which is also called radical experimental budget, can test the The higher OH concentration at the Backgarden site was closely aPeak values in the diurnal profiles. 1, this site, which belongs to the urban site, is located in the university town and is surrounded by residential and the uncertainties of measurements and simulations. measurements of OH and the key trace gases are available in the study. and the maximum of the median ratios existed when NO concentration was value at daybreak. By allowing and encouraging foreign direct investments, these zones became engines of China's further economic, social, urban, and political development. The most significant difference between the above is that concentrations were 4.5106 and 3.5106cm3.

The Republic of China (ROC), between 1912 and 1949, was a sovereign state recognised as the official designation of China when it was based on Mainland China, prior to the relocation of its central government to Taiwan as a result of the Chinese Civil War.At a population of 541 million in 1949, it was the world's most populous country.Covering 11.4 million square kilometres (4.4 Radicals, the Among these clusters, Guangzhou Economic and Technological Development Zone, Foshan National High-Tech Industrial Development Zone and Zhaoqing High-Tech Industrial Development Zone are located within the GBA.
