A dual attentional skip connection based Swin‐UNet for real‐time cloud segmentation

IET Image Processing, Volume 18, Issue 12, Page 3460-3479, 16 October 2024.
We propose a swin transformer based encoder‐decoder network, by incorporating a dual attentional skip connection with Swin‐UNet (DASUNet) for cloud segmentation. DASUNet characterizes the less salient features by equipping with token dual attention modules among the skip connection. The token dual attention module consists of token similarity attention

Seasonal, Interannual and Long‐Term Variability of Sea Surface Temperature in the NW Iberian Upwelling, 1982–2020

Journal of Geophysical Research: Oceans, Volume 129, Issue 9, September 2024.
Abstract Here the seasonal, inter‐annual and long‐term variability of satellite‐derived sea surface temperature (SST) was analyzed in the NW Iberian margin from 1982 to 2020 to explore spatial differences at high (5‐km) resolution. In‐situ temperature measurements from five coastal buoys were used to validate the satellite‐derived SST data, discarding ...

Lake Water Temperature Modeling in an Era of Climate Change: Data Sources, Models, and Future Prospects

Reviews of Geophysics, Volume 62, Issue 1, March 2024.
Abstract Lake thermal dynamics have been considerably impacted by climate change, with potential adverse effects on aquatic ecosystems. To better understand the potential impacts of future climate change on lake thermal dynamics and related processes, the use of mathematical models is essential.

Air Temperature Modeling Based on Land Surface Factors by the Cubist Method (Case Study of Hamoun International Wetland)

Advances in Meteorology, Volume 2024, Issue 1, 2024.
The drying up of Hamoun International Wetland (HIW) and the loss of vegetation in this area have led to an increase in ambient temperature. This research examines the changes in the surface of HIW and its role in air temperature (Tair) using data on land surface temperature (LST), vegetation, wind speed, and relative humidity.

Trends in Nighttime Fires in South/Southeast Asian Countries

Atmosphere
Quantifying spatial variations and trends in nighttime fires is crucial for a comprehensive understanding of fire dynamics. Traditional fire monitoring typically focuses on daytime observations, but controlling nocturnal fires poses unique challenges due

Drought Index Mapping in Java Island Using Sentinel-3 SLSTR

International Journal of Geoinformatics, 2021
As the most populous island globally, Java Island has various vulnerabilities to disasters ranging from geological to hydro-meteorological. One of the most common hydro-meteorological disasters is the drought that occurs every year in the dry season. This disaster causes crop failure, land and forest fires, and clean water shortages. In this study, the
