Retrieval of Snow Depths on Arctic Sea Ice in the Cold Season from FY-3D/MWRI Data

Remote Sensing
Snow depth is a crucial factor in the formation of snow, and its fluctuations play a significant role in the Earth’s climate system. The existing snow depth algorithms currently lack systematic quantitative evaluation, and most of them are not suitable ...

Intercalibration of FY-3C MWRI Against GMI Using the Ocean Microwave Radiative Transfer Model

IEEE Access, 2020
This work addresses the intercalibration of the Microwave Radiation Imager (MWRI) on the Chinese second-generation polar-orbiting meteorological satellite Fengyun 3C (FY-3C) against the Microwave Imager (GMI) on the Global Precipitation Measurement (GPM)

The effective use of anchor observations in variational bias correction in the presence of model bias

Quarterly Journal of the Royal Meteorological Society, Volume 149, Issue 754, Page 1789-1809, July 2023 Part A., 2023
Satellite radiance data offer valuable information to enhance numerical weather prediction. Often these data need to be bias‐corrected before they can be used, and are corrected in data assimilation using a variational bias‐correction technique known as VarBC. However, model bias can contaminate the correction of observation bias.

Assimilation of data from the MWHS‐II onboard the first early morning satellite FY‐3E into the CMA global 4D‐Var system

Meteorological Applications, Volume 30, Issue 3, May/June 2023., 2023
The MWHS‐II onboard FY‐3E, the first early morning satellite in‐orbit running no more than 8 months, is evaluated in the CMA operational global numerical weather prediction system. Its observations improve global observation coverage over a 3‐h time period.

Plot size and sustainable input intensification in smallholder irrigated agriculture: Evidence from Egypt

Agricultural Economics, Volume 53, Issue 5, Page 792-810, September 2022., 2022
Abstract Increasing population pressure and population density in many African countries are inducing land scarcity and land constraints. Tightening land constraints are expected to trigger various responses, including agricultural intensification, as postulated by the Boserup hypothesis. The relevance of the Boserup hypothesis in irrigated agriculture,

Potential impacts of failure of the Grand Ethiopian Renaissance Dam on downstream countries

Journal of Flood Risk Management, Volume 15, Issue 2, June 2022., 2022
Abstract This study assesses the potential downstream impacts in the event of a flood due to failure, either structural or operational, of the Grand Ethiopian renaissance dam (GERD). The following two failure scenarios were modeled as part of this study: Dam Break (DB) and MisGuided Dam Operation (MGDO) as a result of a false flood signature.
