Super-Resolution of Radar/Raingauge-Analyzed Precipitation Using Gaussian Process Regression with a Steering Kernel

Shoichi Akami, Tsuyoshi T. Sekiyama, Mizuo Kajino

Super-resolution (SR), a technique for estimating a high-resolution (HR) image from a low-resolution image, has been used in meteorology for downscaling and resolution enhancement of observations. SR Gaussian process regression with a steering kernel (SRGP-SK) generates more accurate HR images than the …

Characteristics of Drizzle Mode in the Raindrop Size Distribution Observed at Mount Tsukuba

Ryohei Misumi, Katsuya Yamashita, Hiroyuki Kusaka, Mizuo Kajino

Abstract Raindrop size distribution (RDSD) is crucial for radar-based precipitation estimation and validating numerical simulation models, especially in mountainous regions where accurate rainfall data are vital for water resource management and disaster mitigation. Previous studies suggest that orographic rainfall is characterized by …

Super-Resolution Surrogate Downscaling of MRI-ESM2(CMIP6) Black Carbon Surface Concentration Using Attention Based Convolutional Neural Networks

Kunal Mishra, Mizuo Kajino, Tsuyoshi Thomas Sekiyama, Naga Oshima

Tropospheric Black Carbon (BC) aerosols are short lived positive radiative forcer with critical impacts on cardiovascular and pulmonary health. The MRI-ESM2(CMIP6) delivers the BC monthly global surface concentration from 1950-2100 at coarse special resolution of 1.875° × 1.875° which does not capture …

Disentangling the Separate and Combined Effects of Aerosol‐Radiation and Aerosol‐Photolysis Interactions on Air Quality Over India

Arshitha Anand K A, Dilip Ganguly, Indranil Nandi, Mizuo Kajino et autres

Abstract This study examines the individual and combined impacts of aerosol‐radiation interactions (ARI) and aerosol‐photolysis interactions (API) on regional air quality over India using the WRF‐Chem model for May 2018. Model performance was validated against CERES, MERRA‐2, and CPCB observations, demonstrating good …

Impact of post-monsoon crop residue burning on PM 2.5 over northern India: optimizing emissions using a high-density in situ surface observation network

Mizuo Kajino, Kentaro Ishijima, Joseph Ching, Kazuyo Yamaji et autres

The impact of post-monsoon crop residue burning (CRB) on surface PM 2.5 concentrations over the Punjab–Haryana–Delhi (PHD) region in northern India was investigated using a regional meteorology–chemistry model, NHM(WRF)-Chem, and a high-density in situ surface observation network comprising Compact and Useful PM …

Continual tropical cyclone and extreme urban heat (TC-Heat) compound events under East Asian metropolitan cities’ footprint

Jeffrey Man‐Hei Chang, Yun Fat Lam, Mizuo Kajino

The development of megacities and irreversible trends in global warming have brought us new hazards through compound extreme weather events in the urban society. Extreme hot days are occasionally observed with subsidence and stagnant air conditions driven by far-distance approaching tropical cyclones. …
