Adaptive neuro fuzzy inference system for predicting sub-daily Zenith Wet Delay

Geodesy and Geodynamics, 2022
In recent years, the focus of tropospheric studies has evolved to GNSS meteorology and weather forecasting. The Zenith Wet Delay (ZWD), which might be assembled to the Integrated Water Vapour (IWV), is an essential component of the tropospheric delay ...

Can Solar‐Powered Irrigation Systems Naturally Meet Crop Water Requirements? Proof of Concept From a Case Study in Sub‐Saharan Africa

Irrigation and Drainage, EarlyView.
ABSTRACT Irrigation scheduling is crucial for ensuring precise water delivery to crops. However, in many sub‐Saharan African irrigation schemes, water is applied without considering crop water needs, resulting in low crop water productivity and low yields. Solar‐powered irrigation systems can automatically meet these needs by utilizing solar radiation,

An Improved IASI Temperature and Humidity Retrieval Method Based on Double Channel Differences

Earth and Space Science, Volume 9, Issue 12, December 2022., 2022
Abstract Due to surface emissivity, the retrieval accuracy of hyperspectral infrared temperature and humidity profiles is typically poor in the lower atmosphere. To solve this problem, we use the double channel differences method (DCDM) to retrieve the temperature and humidity profiles of the Infrared Atmospheric Sounding Interferometer (IASI) with ...

Modelling the Impact of Drained and Undrained Conditions on GHG Emissions in Croplands: A Case Study in Lincolnshire, UK

Irrigation and Drainage, EarlyView.
ABSTRACT Agricultural drainage plays a crucial role in land management and crop productivity but significantly impacts greenhouse gas (GHG) emissions. This study examines the effects of drained and undrained soil conditions on GHG emissions in croplands via a case study in Lincolnshire, United Kingdom.

Characterizing Drivers of Asia's Black Elephant Disaster Risks

Earth's Future, Volume 10, Issue 12, December 2022., 2022
Abstract Asia has the fastest growing population and economy, but it is also the most disaster‐prone region in the world. Resilience to disaster impacts from natural hazards will be key to the long‐term sustainability of this rapidly growing region. The first step to building resilience is to identify the key threats that this region faces. We describe

Optimizing sampling across transect‐based methods improves the power of agroecological monitoring data

Journal of Environmental Quality, EarlyView.
Abstract Transect‐based monitoring has long been a valuable tool in ecosystem monitoring to measure multiple ecosystem attributes. The line‐point intercept (LPI), vegetation height, and canopy gap intercept methods comprise a set of core methods, which provide indicators of ecosystem condition.
