Radiation Component Calculation and Energy Budget Analysis for the Korean Peninsula Region

Remote Sensing, 2018
In this study, a radiation component calculation algorithm was developed using channel data from the Himawari-8 Advanced Himawari Imager (AHI) and meteorological data from the Unified Model (UM) Local Data Assimilation and Prediction System (LDAPS).

Earth’s Energy Imbalance Measured From Space [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2019
The direct measurement of earth’s energy imbalance (EEI) is one of the greatest challenges in climate research. The global mean EEI represents the integrated value of global warming and is tightly linked to changes in hydrological cycle and the habitability of our planet. Current space-born radiometers measure the individual radiative components of the

Earth's Energy Imbalance From the Ocean Perspective (2005–2019)

Geophysical Research Letters, 2021
Earth's energy imbalance (EEI) represents the rate of global energy accumulation in response to radiative forcings and feedbacks. Ocean heat uptake (OHU) poses a vital constraint on EEI and its uncertainty.

Earth's Energy Imbalance: Confirmation and Implications

Science, 2005
Our climate model, driven mainly by increasing human-made greenhouse gases and aerosols, among other forcings, calculates that Earth is now absorbing 0.85 ± 0.15 watts per square meter more energy from the Sun than it is emitting to space. This imbalance is confirmed by precise measurements of increasing ocean heat content over the past 10 years ...

Climate models with moderate climate sensitivity best simulate the magnitude of Earth's energy imbalance [PDF]

Earth System Dynamics
Recent studies have highlighted that state-of-the-art climate models are not able to simulate the large observed trend in Earth's energy imbalance. Here we evaluate climate models' ability to represent both the trend and the magnitude of the imbalance ...

Self-Consistent Energy Normalization for Quasistatic Reactor Calculations

Journal of Nuclear Engineering, 2021
Use of the quasistatic (keff) approximation for producing steady-state solutions for non-critical fission systems is known to result in an imbalance between energy release and deposition within the system.

Grid-Following Mode Operation of Small-Scale Distributed Battery Energy Storages for Fast Frequency Regulation in a Mixed-Source Microgrid

Energies, 2021
As the share of power converter-based renewable energy sources (RESs) is high, a microgrid, in islanded mode, is more vulnerable to frequency instability due to (1) sudden power imbalance and (2) low inertia.
