Our meta-analysis indicates that a 30% #SNF (synthetic #nitrogen #fertilizer)reduction is achievable without significant yield loss on average on crop yield and would reduce N waste from Japanese cropland by 8.8%. doi.org/10.1016/j.jenv…

Our study validates the #GreenhouseGas #satelliteproducts including Sentinel-5, OCO-2, and GOSAT using #COCCONdata, a fiducial reference measurement (FRM), and the overall good agreement for #GOSAT XCO2 was found with a mean R2value of 0.850 for all sites. doi.org/10.3390/rs1705…

Continuous hourly monitoring data of #AirQuality (#SO2, #NO, #NO2, #O3, #CH4, #NMHC, #SPM and PM2.5) and meteorological elements at Atmospheric Measurement and Experiment Laboratory of NIES in Tsukuba, Japan from 1995 to 2022 is now available. nies.go.jp/doi/10.17595/2…

Our study presents VISIT-SIF, a new #biogeochemicalprocess-based #carbon and #nitrogen cycle model for representing #SIF retrievals acquired by #GOSAT reproduced the global distribution and seasonal variations in observed SIF. doi.org/10.5194/gmd-18…

Our study reveals that #marine #bacteria may indirectly influence the distribution of #acetaldehydeby demonstrating the photoproduction of atmospherically reactive organic compounds from marine bacteria-derived dissolved organic matter. doi.org/10.1021/acs.es… #DOM #CDOM #FDOM

Onion-like #nanoparticles, primarily single spherical particles with diameters of ∼10–20 nm, were first observed in turbofan jet engines by high-resolution transmission electron microscopy. doi.org/10.1021/acsest…

We revisit #ozone trends over 1998–2018 using new chemistry-climate models and find that stratospheric ozone trends are related to transport trends and the differences between models come from differences in ozone transport and its interannual variability. doi.org/10.1029/2024JD…

Global #Biomass Burning Emissions Inventory (GBEI) in 2024 is now available. We created 8 global CO2 emission inventories through fires by combining input data sources and provide #CO2/#CO/#CH4 emissions calculated using this combination data. doi.org/10.17595/20230…

／ 温室効果ガス観測技術衛星 #GOSATGW の観測データどう使う？🛰 ＼ 6月末にGOSATGW（愛称 #いぶきGW ）が打ち上げられました🌎 #脱炭素ポータル では、GOSATプロジェクトに関わる環境省・岡野祥平氏と国環研・谷本浩志氏が対談✨ 自治体や企業における観測データの活用方法について語ります👇

Now available: Continuous #CO2 and #CH4 data observed at Hateruma Island and Cape Ochiishi. The Hateruma CO2 data represent the subtropics of the East Asian region, reflecting Pacific air in summer and continental Asian air in winter. doi.org/10.17595/20160…

The latest version of #CO2 mole fractions observed by Continuous CO2 Measuring Equipment (#CME) and trace gas mole fractions observed over the #Eurasian continent by the flask air sampling from the #CONTRAIL is released. doi.org/10.17595/20210… doi.org/10.17595/20230…

Mobile measurements of #methane and #ethane from more than 2000 km long vehicle drives in the Tokyo area (Sep–Oct 2023) are now available. Vehicle position and wind data were also recorded. doi.org/10.17595/20251…

High-resolution, bias-corrected #climate simulation data is now available. It includes 10 variables with daily temporal and 0.5° spatial resolution, based on 38 CMIP6 models, supporting impact and uncertainty analyses under historical and future scenarios. doi.org/10.17595/20251…

Atmospheric #BlackCarbon (#BC) mass concentration data from ground-based observations  in Ogata Village, Akita (Dec 2022) is now available. doi.org/10.17595/20251…

#Micrometeorological #CO2 Flux Data includes #ecosystem CO2 flux, and sensible and latent heat flux at Fuji Hokuroku Flux Observation Site (FHK) has been released with the additional 2013-2023 data. db.cger.nies.go.jp/ged/en/index.h…

Sector-wise, multi-resolution #wateruse dataset of Japan with long-term data (1950–) for #industrial, #domestic, and #paddyfield sectors is now available. The spatial resolution options were 1 km grids, prefectures, and cities.　nies.go.jp/doi/10.17595/2…
