Rain rate statistical conversion for the predictionof rain attenuation in Malaysia

Electronics Letters, 1999
The transformation of hourly rain rate data into equivalent one-minute statistics is very useful for microwave systems designers since the hourly rainfall data are more abundant and can be obtained at many locations. An empirical model is proposed for approximating the rain rate conversion factor from 1 h to 1 min integration time in Malaysia.

Drought Risk in Mango and Avocado Orchards: Insights Into Plant Water Relations and Irrigation‐Related Agronomic Solutions

Irrigation and Drainage, EarlyView.
ABSTRACT Climate change is making water availability more uncertain, with growing consequences for the productivity and long‐term sustainability of tropical and subtropical fruit orchards. Mangifera indica L. and Persea americana Mill. both require large amounts of water to sustain growth and productivity.

Analysis of Radiative Transfer Characteristics of a Spherical Continuous-Spectrum Light Source Under Rainfall Conditions

Photonics
The current research on light transmission under rainfall conditions primarily focuses on monochromatic converging light sources, and the related conclusions cannot be directly applied to spherical continuous-spectrum light sources (SCLSs).

Healthier Herds, Heavier Workloads? The Gendered Time and Resource Implications of Herd Health Management in Kenyan Dairy Systems

Journal of International Development, EarlyView.
ABSTRACT Strategies for sustainable intensification of livestock are critical for food system transformation. In dairying systems, herd health management is among such strategies. Although adoption patterns and productivity gains have been analysed in previous studies, the social implications are still not well understood.

Analysis of Cross-Polarization Discrimination Due to Rain for Earth–Space Satellite Links Operating at Millimetre-Wave Frequencies in Pretoria, South Africa

Atmosphere
This study investigates the impact of rain-induced attenuation on cross-polarization discrimination (XPD) in Earth–space satellite links operating at millimeter-wave frequencies in Pretoria, South Africa. The traditional method of computing XPD employs a

Analysis of Climate Variability of Homogeneous Regions of Rainfall Anomalies in Southeast South America (SESA)

International Journal of Climatology, EarlyView.
We studied rainfall variability and cyclicity in six Homogeneous Regions of Rainfall Anomalies (HRRA) in Southeast South America (SESA) from 1961 to 2020 to understand the occurrence of droughts and above‐average rainfall. We use a continental analysis scale, focusing on seasonal, interannual, and interdecadal cycles, and their association with modes ...

Rain fade impairment analysis for Earth-to-space radio links using site diversity techniques in Delta State, Nigeria

African Scientific Reports
Site diversity is a fade mitigation technique that employs two or more spatially separated receiving stations to reduce the adverse effects of rain attenuation on satellite communication links.

Early deglaciation history of the southeastern Baffin Island shelf (Eastern Canadian Arctic Archipelago)

Journal of Quaternary Science, EarlyView.
ABSTRACT During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ...

Rain Rate Measurements & Rain Attenuation Studies at 7 GHz Northern India [PDF]

, 1980
47-51Rain attenuation is an important parameter to be accounted for in tropospheric propagation of frequencies above 10 GHz. But during the monsoon period even lower frequencies around 7 GHz are appreciably affected.

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...
