Abstract. Arctic rain on snow (ROS) deposits liquid water onto existing snowpacks. Upon refreezing, this can form icy crusts at the surface or within snowpack. By altering radar backscatter and microwave emissivity, ROS over sea ice influence accuracy of variables retrieved from satellite altimetry, scatterometers, passive radiometers. During Ocean MOSAiC (Multidisciplinary drifting Observatory...

Polar sea ice profoundly affects atmospheric and oceanic circulation plays a significant role in climate change. Sea concentration (SIC) is key geophysical parameter used to quantify these changes. In this study, we determined SIC products for the Arctic Antarctic from 2019 2021 using data Chinese marine satellite Haiyang 2B (HY-2B) with an improved bootstrap algorithm. Then results were compar...

Meso- and fine-scale sea surface temperature (SST) is an essential parameter in oceanographic research. Remote sensing efficient way to acquire global SST. However, single infrared-based microwave-based satellite-derived SST cannot obtain complete coverage high-resolution simultaneously. Deep learning super-resolution (SR) techniques have exhibited the ability enhance spatial resolution, offeri...

Accurate snow water equivalent (SWE) products are vital for monitoring hydrological processes and managing resources effectively. However, the coarse spatial resolution (typically at 25 km from passive microwave remote sensing images) of existing SWE cannot meet needs explicit modeling. Linear regression ignores autocorrelation (SA) in variables, measure SA data assimilation algorithm is not ex...

Abstract. Sea surface temperature (SST) is an important geophysical parameter that essential for studying global climate change. Although sea can currently be obtained through a variety of sensors (MODIS, AVHRR, AMSR-E, AMSR2, WindSat, in situ sensors), the values by different come from ocean depths and observation times, so products lack consistency. In addition, thermal infrared have many inv...

The integrated Multi-satellitE Retrievals for GPM (IMERG) Version V05B and V06B precipitation products from the Global Precipitation Measurement (GPM) mission are validated against ground-based observations Kwajalein Polarimetric S-band Weather Radar (KPOL) deployed at Atoll in central Pacific Ocean. Such a validation is particularly important as comprehensive surface measurements over oceans p...

Abstract. Widely used sea ice concentration and cover in polar regions are derived mainly from spaceborne microwave radiometer scatterometer data, the typical spatial resolution of these products ranges several to dozens kilometers. Due dramatic changes ice, high-resolution data drawing increasing attention for navigation, environmental research, offshore operations. In this paper, we focused o...

This paper aims to test the ability of WRF-Chem model simulate sand storms in Northwest China and improve simulation results by introducing remote sensing soil moisture data into WRF-Chem. We conducted sensitivity tests, including parameterization scheme tests using By comparing various combinations schemes, which have considerable impacts on emissions, most suitable for was selected establishi...
