Evaluation and assimilation of Arctic Weather Satellite data in the AROME‐Arctic forecast system

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The Arctic Weather Satellite (AWS), launched in August 2024, is a prototype for the future EPS–Sterna constellation of small satellites carrying an innovative microwave sounder. We present the first assessment of AWS in the regional AROME‐Arctic numerical weather prediction system, covering post‐launch calibration results and the impact of AWS ...

Estimation of All-Sky Gridded Diurnal Near-Surface Air Temperatures at Regional Scale From FY-4B Measurements

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The near-surface air temperature (${{T}_{air}}$) is a principal variable describing energy exchange and water circulation between the land surface and the atmospheric environment. The estimation of ${{T}_{air}}$ by satellite land surface temperature (LST)

Multiscale controls on diurnal convection in the Maritime Continent: Insights from high‐resolution observations in Timika

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Across the Maritime Continent, diurnal rainfall variability is governed by interactions between regional‐scale atmospheric drivers and local land–sea breeze circulations. Afternoon convection is initiated over land by surface heating and propagates offshore, whereas morning rainfall develops over adjacent seas and moves inland under low‐level northerly

Accurate Satellite Operation Predictions Using Attention-BiLSTM Model with Telemetry Correlation

Aerospace
In satellite health management, anomalies are mostly resolved after an event and are rarely predicted in advance. Thus, trend prediction is critical for avoiding satellite faults, which may affect the accuracy and quality of satellite data and even ...

Satellite Assessments of Tropopause Dry Intrusions Correlated to Mid-Latitude Storms

Atmosphere, 2016
Dry intrusion is an important mid-latitude atmosphere phenomenon within the upper troposphere and lower stratosphere. It is often found to be related to the cyclogenesis, rainstorm, as well as convection generation and precipitation enhancement.
