Abstract	Elevation gradients, often regarded as "natural experiments or laboratories", can be used to study changes in the distribution of microbial diversity related to changes in environmental conditions that typically occur over small geographical scales. We exploited this feature by characterizing fungal composition and diversity along an elevation gradient on Xinglong Mountain, northwest China. For this, we used MiSeq sequencing to obtain fungal sequences and clustered them into operational taxonomic units (OTUs). In total, we obtained 1,203,302 reads, 133,700 on average in each sample of soil collected at three selected elevations (2807, 3046, and 3536 m). The reads were assigned to 2192 OTUs. Inconsistent variations were observed in fungal alpha-diversity in samples from the three elevations. However, Principal Coordinate Analysis based on Bray-Curtis and UniFrac (weighted and unweighted) distance metrics revealed that fungal communities in soil samples from 3046 and 3536 m elevations were most similar. Principal Component Analysis based on relative abundances of shared OTUs confirmed that OTUs in samples from 3536 m elevation were more closely related to OTUs from 3046 m than samples from 2807 m elevation. Ascomycota, Basidiomycota, Glomeromycota, Cercozoa and Chytridiomycota were the most abundant fungal phyla across the elevation gradient. Our study also provides valuable indications of relations between fungal communities and an array of soil chemical properties, and variations in fungal taxonomic diversity across a substantial elevation gradient.

Abstract	High-accuracy continuous measurements of atmospheric concentrations of CO2 were made from May 2016 to December 2017 using the Picarro G2301 analyzer at Xinglong station (40°24′N, 117°30′E, 940 MSL), 150 km northeast of Beijing. The near-ground CO2 measurements were calibrated by standards based on WMO procedures. The regional background measurements were filtered by the robust extraction of baseline signal method to study the seasonal and diurnal cycles. The regional background CO2 concentrations were low in summer. The maximum difference between the local sources and regional background CO2 concentrations occurred in summer and autumn, indicating a strong influence from local sources. Cluster analysis and potential source contribution function analysis showed that the long-distance transport of anthropogenic emissions in the Beijing–Tianjin–Hebei metropolitan area influenced the CO2 concentrations in Xinglong, especially in summer. The diurnal variation of CO2 was mainly influenced by the various vertical transport conditions of the tropospheric atmosphere in a day.

Abstract	Atmospheric CO 2 mole fractions are observed at Beijing (BJ), Xianghe (XH), and Xinglong (XL) in North China using Picarro G2301 cavity ring-down spectroscopy instruments. The measurement system is described comprehensively for the first time. The geographical distances among these three sites are within 200 km , but they have very different surrounding environments: BJ is inside the megacity; XH is in the suburban area; XL is in the countryside on a mountain. The mean and standard deviation of CO 2 mole fractions at BJ, XH, and XL between October 2018 and September 2019 are 448.4±12.8 , 436.0±9.2 , and 420.6±8.2 ppm , respectively. The seasonal variations of CO 2 at these three sites are similar, with a maximum in winter and a minimum in summer, which is dominated by the terrestrial ecosystem. However, the seasonal variations of CO 2 at BJ and XH are more affected by human activities as compared to XL. Using CO 2 at XL as the background, CO 2 enhancements are observed simultaneously at BJ and XH. The diurnal variations of CO 2 are driven by the boundary layer height, photosynthesis, and human activities at BJ, XH, and XL. We also compare the CO 2 measurements at BJ, XH, and XL with five urban sites in the USA, and it is found that the CO 2 mean concentration at BJ is the largest. Moreover, we address the impact of the wind on the CO 2 mole fractions at BJ and XL. This study provides an insight into the spatial and temporal variations of CO 2 mole fractions in North China.

Abstract	Size-segregated aerosol samples were collected using Andersen cascade sampler from Sep. 2009 to Aug. 2010 in Xinglong, a regional atmospheric background station. The water-soluble inorganic ions were analyzed by IC. The result showed that the annual concentrations of the total water-soluble inorganic ions were (89.66 +/- 47.66), (54.44 +/- 34.08) and (44.39 +/- 29.95) microg x m(-3) in TSP, PM2.1 and PM1.1 respectively. SO4(2-), NO3(-), Ca(2) and NH4(+) were the dominant contributors of water-soluble inorganic ions. The total water-soluble inorganic ions in PM2.1 accounted for 61% of TSP. The total water-soluble inorganic ions in PM1.1 accounted for 50% and 82% in TSP and PM2.1, respectively. The seasonal variations of the total water-soluble inorganic ion concentration in TSP, PM2.1 and PM1.1 were the same, following the order of summer > autumn > springs > winter. The mean molar ratio of NH4(+) to SO4(2-) was larger than 2, indicating that NH4(+) was not completely neutralized by SO4(2-). NH4(+) -SO4(2-) and NH4(+) -NO3(-) concentrations were strongly correlated (R2 0.96 and 0.87), indicating that NH4(+) was mainly present as (NH4) 2SO4 and NH4NO3.

Abstract	In this study, Terra-MODIS (Moderate Resolution Imaging Spectroradiometer) Collections 6 and 6.1 (C6 & C6.1) aerosol optical depth (AOD) retrievals with the recommended high-quality flag (QF = 3) were retrieved from Dark-Target (DT), Deep-Blue (DB) and merged DT and DB (DTB) level⁻2 AOD products for verification against Aerosol Robotic Network (AERONET) Version 3 Level 2.0 AOD data obtained from 2004⁻2014 for three sites located in the Beijing-Tianjin-Hebei (BTH) region. These are: Beijing, located over mixed bright urban surfaces, XiangHe located over suburban surfaces, and Xinglong located over hilly and vegetated surfaces. The AOD retrievals were also validated over different land-cover types defined by static monthly NDVI (Normalized Difference Vegetation Index) values obtained from the Terra-MODIS level-3 product (MOD13A3). These include non-vegetated surfaces (NVS, NDVI < 0.2), partially vegetated surfaces (PVS, 0.2 ≤ NDVI ≤ 0.3), moderately vegetated surfaces (MVS, 0.3 < NDVI < 0.5) and densely vegetated surfaces (DVS, NDVI ≥ 0.5). Results show that the DT, DB, and DTB-collocated retrievals achieve a high correlation coefficient of ~ 0.90⁻0.97, 0.89⁻0.95, and 0.86⁻0.95, respectively, with AERONET AOD. The DT C6 and C6.1 collocated retrievals were comparable at XiangHe and Xinglong, whereas at Beijing, the percentage of collocated retrievals within the expected error (↔EE) increased from 21.4% to 35.5%, the root mean square error (RMSE) decreased from 0.37 to 0.24, and the relative percent mean error (RPME) decreased from 49% to 27%. These results suggest significant relative improvement in the DT C6.1 product. The percentage of DB-collocated AOD retrievals ↔EE was greater than 70% at Beijing and Xinglong, whereas less than 66% was observed at XiangHe. Similar to DT AOD, DTB AOD retrievals performed well at XiangHe and Xinglong compared with Beijing. Regionally, DB C6 and C6.1-collocated retrievals performed better than DT and DTB in terms of good quality retrievals and relatively small ...

Abstract	Chalcogen bonding catalysis with divalent chalcogenides required using heteroatoms as electron donors to give reactivity, while the activation of hydrocarbons such as alkenes by this concept remains an unresolved challenge. Herein, we discovered a powerful selenide catalyst that showed unprecedented capability in the activation of alkenes. The Se⋅⋅⋅π interactions were capable of catalyzing a broad range of transformations, including intermolecular cyclization and coupling reactions. Significantly, the Se⋅⋅⋅π bonding activation mode can be exploited to achieve intermolecular enyne cyclizations and controlled cross-coupling of triple alkenes. The activation of alkenes by divalent selenides opens up a new avenue for supramolecular catalysis.
