In this paper, we present Pangu-Weather, a deep learning based system for fast and accurate global weather forecast. For purpose, establish data-driven environment by downloading $43$ years of hourly data from the 5th generation ECMWF reanalysis (ERA5) train few neural networks with about $256$ million parameters in total. The spatial resolution forecast is $0.25^\circ\times0.25^\circ$, comparable to Integrated Forecast Systems (IFS). More importantly, first time, an AI-based method...
Abstract Methanol is the second‐most abundant organic gas in remote atmosphere after methane, but its sources are poorly understood. Here, we report a global budget of methanol constrained by observations from ATom aircraft campaign as implemented GEOS‐Chem atmospheric chemistry model. under background marine conditions can be fit model with surface ocean concentration 61 nM and yield 13% newly CH 3 O 2 + OH reaction. While terrestrial biogenic emissions dominate budget, secondary production...
Abstract. The global oxidation capacity, defined as the tropospheric mean concentration of hydroxyl radical (OH), controls lifetime reactive trace gases in atmosphere such methane and carbon monoxide (CO). Models tend to underestimate CO concentrations throughout troposphere, which is consistent with excessive OH. Approximately half non-methane volatile organic compounds (VOCs) thought occur over oceans where oxidant chemistry has received little validation due a lack observational...
Terrestrial ecosystems are simultaneously the largest source and a major sink of volatile organic compounds (VOCs) to global atmosphere, these two-way fluxes an important uncertainty in current models. Here, we apply high-resolution mass spectrometry (proton transfer reaction-quadrupole interface time-of-flight; PTR-QiTOF) measure ecosystem–atmosphere VOC across entire detected range (m/z 0–335) over mixed temperate forest use results test how well state-of-science chemical transport model...
Formic acid (HCOOH) is among the most abundant carboxylic acids in atmosphere, but its budget poorly understood. We present eddy flux, vertical gradient, and soil chamber measurements from a mixed forest apply data to better constrain HCOOH source/sink pathways. While cumulative above-canopy flux was downward, exchange bidirectional, with extended periods of net upward downward flux. Net fluxes were mostly during warmer/drier periods. The implied gross canopy source corresponds 3% 38%...
Abstract. We apply a high-resolution chemical transport model (GEOS-Chem CTM) with updated treatment of volatile organic compounds (VOCs) and comprehensive suite airborne datasets over North America to (i) characterize the VOC budget (ii) test ability current models capture distribution reactivity atmospheric VOCs this region. Biogenic emissions dominate American in model, accounting for 70 % 95 annually emitted carbon reactivity, respectively. Based on inventories anthropogenic have...
Abstract Methane (CH4) and nitrous oxide (N2O) emissions from an irrigated rice field under continuous flooding intermittent irrigation water management practices in northern China were measured situ by the static chamber technique during May to October 2000. The reduced total growing‐season CH4 emission 24.22% but increased N2O 23.72%, when compared with flooding. Soil Eh four related bacterial groups also clarify their effects on gaseous emissions. Three ranges of soil redox potential gas...
Formic acid (HCOOH) is an important component of atmospheric acidity but its budget poorly understood, with prior observations implying substantial missing sources. Here, we combine pole-to-pole airborne from the Atmospheric Tomography Mission (ATom) a chemical transport model (GEOS-Chem CTM) and back-trajectory analyses to provide first global in situ characterization HCOOH remote atmosphere. ATom reveals sub-100 ppt concentrations over most oceans, punctuated by large enhancements...
India is an air pollution mortality hot spot, but regional emissions are poorly understood. We present a high-resolution nested chemical transport model (GEOS-Chem) simulation for the Indian subcontinent and use it to interpret formaldehyde (HCHO) observations from two satellite sensors (OMI GOME-2A) in terms of constraints on volatile organic compound (VOC) emissions. find modeled biogenic VOC be overestimated by ~30-60% most locations seasons, derive best estimate flux 16 Tg C/year...

In order to study and forecast extreme weather, a comprehensive systematic analysis of the spatial temporal relationship between Precipitable Water Vapor (PWV), predicted by Numerical Weather Predication (NWP) data, precipitation, is necessary. The goal this paper was PWV precipitation during so-called ‘July 20’ (18–21 July 2021) heavy rainstorm in Zhengzhou. Firstly, data provided 120 radiosonde stations uniformly distributed throughout world, two IGS China, 2020, used evaluate accuracy...
Abstract Agriculture and waste are thought to account for half or more of the U.S. anthropogenic methane source. However, current bottom‐up inventories contain inherent uncertainties from extrapolating limited in situ measurements larger scales. Here, we employ new airborne over Corn Belt Upper Midwest, among most intensive agricultural regions world, quantify emissions an array key agriculture point sources. Nine largest concentrated animal feeding operations region two sugar processing...
