Assessing the Reliability of Satellite and Reanalysis Estimates of Rainfall in Equatorial Africa

open access: yesRemote Sensing, 2021
This article examines the reliability of satellite and reanalysis estimates of rainfall in the Congo Basin and over Lake Victoria and its catchment. Nine satellite products and five reanalysis products are considered.

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

open access: yesAdvanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Performance evaluation of multi-satellite rainfall products in the Gidabo catchment, Rift Valley Basin, Ethiopia

open access: yesJournal of Water and Climate Change, 2023
Satellite rainfalls are good options to overcome shorter records, record challenges and inconsistencies with rain-gauges. However, satellites' rainfall retrieval algorithms are region-time scale specific; hence, the key concern is selection of ...

Evaluation of Satellite Rainfall Estimates for Swaziland [PDF]

open access: yesAmerican Journal of Agriculture and Forestry, 2015
Swaziland is generally an arid country, with most rains falling during the period of October to March. The long term average annual rainfall ranges from 400 mm in the lowveld to 1,200 mm in the mountainous highveld. Raingauges have been used as reliable source of rainfall data, but the density of these ground based instruments is too low, offering poor

Evaluation and Reliability of CHIRPS Satellite Rainfall Products Against Station Rainfall Data in the Siwaluh Basin

open access: yesEngineering Proceedings
The characteristics of rainfall in the Siwaluh river basin are poorly understood due to a lack of data. Many rainfall data are missing and many rain gauge posts are damaged.

Technical Feasibility Study of Autonomous Field Robot‐Based on‐the‐go Assessment of Soil Nutrients Using Ion‐Sensitive Field‐Effect Transistors

open access: yesAdvanced Robotics Research, EarlyView.
Autonomous field robots equipped with ISFET‐based sensors enable rapid, spatially resolved soil nutrient analysis directly in the field. An automated system based on the BoniRob platform is presented for standardized on‐site extraction and measurement of key macronutrients and soil pH.

Evaluation of daily based satellite rainfall estimates for flood monitoring in Gumera Watershed, Amhara region, Ethiopia

open access: yesCogent Social Sciences
In developing countries, including Ethiopia, ground-based rain gauge stations are limited and unevenly distributed. This makes it difficult to find accurate spatial data on the amount of rainfall.

Spatiotemporal Interpolation of Rainfall by Combining BME Theory and Satellite Rainfall Estimates [PDF]

open access: yesAtmosphere, 2015
The accurate assessment of spatiotemporal rainfall variability is a crucial and challenging task in many hydrological applications, mainly due to the lack of a sufficient number of rain gauges. The purpose of the present study is to investigate the spatiotemporal variations of annual and monthly rainfall over Fujian province in China by combining the ...

Rainfall Shapes the Diversity of Soil Nitrogen‐Fixing Microorganisms Worldwide

open access: yesAdvanced Science, EarlyView.
This study reveals the distinctive pattern and mechanism of rainfall driving the global biodiversity and biogeography of soil potential N‐fixing microorganisms, and constructs the theoretical framework. The results guide us on how to maintain ecosystem productivity under future climate changes (e.g., whether a specific region needs more N fertilizers ...
