Development of Drought Monitoring System: I. Applicability of Drought Indices for Quantitative Drought Monitoring

Journal of Korea Water Resources Association, 2006
본 연구에서는 한반도에 대한 가뭄모니터링 시스템을 구축하기 위하여 각종 기상 및 수문자료를 활용하여 우리나라 전역에 대한 PDSI, SPI 및 MSWSI 등의 가뭄지수를 월 단위로 산정 하였으며 산정된 각종 지수들이 어느 정도로 과거에 발생했던 가뭄을 정량적으로 재현하는가를 분석하였다. 분석을 위하여 1994년, 1995년 및 200l년에 발생했던 가뭄의 가뭄피해 조사기록을 이용하였고 본 연구에서 이용되는 3가지의 가뭄지수들이 가뭄감시를 위한 가뭄지표로 활용할 수 있는가를 판단하기 위하여 과거 가뭄에 대한 재현정도, 가뭄단계의 일치성 및 상관관계를 분석하였다. 분석결과, PDSI, SPI(3), SPI(6), MSWSI 순으로

Low Latency Global Carbon Budget Reveals Late 2024 Carbon Losses and Contrasting Early 2025 Land Sink Recovery Signals

Advanced Science, EarlyView.
Low latency carbon budget estimates for July 2024–June 2025 combine atmospheric CO2 growth rates, fossil emissions, ocean uptake, DGVM land fluxes, and OCO‐2 inversions. The budget shows that late‐2024 land carbon losses dominate the annual anomaly, while early‐2025 recovery differs between bottom‐up models and top‐down inversions, especially in ...
