A Novel Electromagnetic Wave Rain Gauge and its Average Rainfall Estimation Method

open access: yesRemote Sensing, 2020
It is essential to accurately estimate rainfall to predict and prevent hydrological disasters such as floods. In this paper, an electromagnetic wave rain gauge system and a method to estimate average rainfall using the system’s multiple elevation ...

Comparison of rain gauge observations with modeled precipitation over Cyprus using contiguous rain area analysis [PDF]

open access: yes, 2005
Verification of modeled rainfall with precipitation observed by a rain gauge network has been performed in a case study over the Cyprus Island. Cyprus has a relatively dense rain gauge network. The applied verification method is the Contiguous Rain Area (

Temporal- and spatial-scale and positional effects on rain erosivity derived from point-scale and contiguous rain data [PDF]

open access: yesHydrology and Earth System Sciences, 2018
Up until now, erosivity required for soil loss predictions has been mainly estimated from rain gauge data at point scale and then spatially interpolated to erosivity maps.

Radar subpixel-scale rainfall variability and uncertainty: lessons learned from observations of a dense rain-gauge network [PDF]

open access: yesHydrology and Earth System Sciences, 2013
Runoff and flash flood generation are very sensitive to rainfall's spatial and temporal variability. The increasing use of radar and satellite data in hydrological applications, due to the sparse distribution of rain gauges over most catchments worldwide,

Rain gauge calibration and testing [PDF]

open access: yes, 1994
Prior to the Tropical Oceans Global Atmosphere-Coupled Ocean Atmosphere Response Experiment (TOGA-COARE), 42 Model 100 series optical gauges were tested in the rain simulator facility at Wallops Island before shipment to the field.

Rain and Snow Gauge Comparisons

open access: yes, 1974
The performance of four types of rain gauges and three methods of measuring snow-fall were compared over a 10 year period. Under the conditions of the test the United States Weather Bureau's (now National Weather Service, NOAA) standard precipitation ...

Modeling run-off flow hydrographs using remote sensing data: an application to the Bashar basin, Iran

open access: yesJournal of Water and Climate Change
Precipitation is hard to access in countries like Iran, due to inadequate number of rain gauge stations. Remote sensing provides an alternative source of rainfall estimation.

Improving Rainfall Erosivity Estimates Using Merged TRMM and Gauge Data

open access: yesRemote Sensing, 2017
Soil erosion is a global issue that threatens food security and causes environmental degradation. Management of water erosion requires accurate estimates of the spatial and temporal variations in the erosive power of rainfall (erosivity).

Rain-Gauge Network Evaluations Using Spatiotemporal Correlation Structure for Semi-Mountainous Regions [PDF]

open access: yes, 2014
A reliable network of rain gauges is a crucial component of rainfall estimation in a watershed. To provide a better evaluation method for rain-gauge networks, a new evaluation method using average inter-gauge correlation coefficients (averaged CC) for ...
