Measuring winter precipitation and snow on the ground in northern polar regions
Measuring winter precipitation in cold and windy regions is recognized as a difficult task. Nonetheless, the accurate measurement of solid precipitation provides important input data for predicting snowmelt floods and avalanche danger and for monitoring climate change. The difficulties in measuring solid precipitation are associated with environmental factors and technological issues. ...

What technology should you choose to measure local rain or water levels?
It can be difficult to select monitoring technology for flooding applications when each step of building a network, from sensors to dataloggers to visualization software, has multiple options. Using OTT HydroMet’s new product brochure with an integrated selection guide, you learn more about: Monitoring network components. Key considerations for selecting sensors, data management ...

Assessment of a 1-hour gridded precipitation dataset to drive a hydrological model: a case study of the summer 2007 floods in the Upper Severn, UK
In this study a gridded hourly 1-km precipitation dataset for a meso-scale catchment (4,062 km2) of the Upper Severn River, UK was constructed using rainfall radar data to disaggregate a daily precipitation (rain gauge) dataset. The dataset was compared to an hourly precipitation dataset created entirely from rainfall radar data. Results found that when assessed against gauge readings and as ...

How will intelligent measurement technology change companies?
In the course of the digital revolution, intelligent measuremen technology is a keystone, since it enables the necessary automation in the first place. Thus, relevant data from smart technology can be collected and evaluated simultaneously. But how does this work exactly and where is the use of intelligent measuring technology a reality already? What is behind the concept of intelligent ...

Lost in calibration: why people still do not calibrate their models, and why they still should – a case study from urban drainage modelling
From a scientific point of view, it is unquestioned that numerical models for technical systems need to be calibrated. However, in sufficiently calibrated models are still used in engineering practice. Case studies in the scientific literature that deal with urban water management are mostly large cities, while little attention is paid to the differing boundary conditions of smaller ...

Spatial and temporal patterns of remotely-sensed and field-measured rainfall in southern California
Quantification of spatial and temporal patterns of rainfall is an important step toward developing regional hydrological models. However, traditionally used rain gauge data are sparse and do not always provide adequate spatial representation of rainfall. In this study, we evaluated the daily 1-degree resolution remotely-sensed atmospheric precipitation data provided by Global Precipitation ...

OTT Pluvio²L in use for a research project in Antarctica - Case Study
Close to McMurdo Station in Antarctica, researchers from the University of Colorado, Boulder and the National Center for Atmospheric Research are investigating methods to measure the accumulating snowfall in the harsh Antarctic environment. These measurements are important to better understand the potential for sea level rise in the future due to climate change. Measuring snowfall in the ...

Comparing the impact of time displaced and biased precipitation estimates for online updated urban runoff models
When an online runoff model is updated from system measurements, the requirements of the precipitation input change. Using rain gauge data as precipitation input there will be a displacement between the time when the rain hits the gauge and the time where the rain hits the actual catchment, due to the time it takes for the rain cell to travel from the rain gauge to the catchment. Since this ...

Measurements of wind-induced loss of solid precipitation: description of a Norwegian field study
Precipitation measurements have a well-documented and mostly wind-dependent bias which is especially apparent during solid precipitation events. The resulting inaccuracy in precipitation data remains an area of concern in quantifying regional and global climate trends. As a high-latitude country, Norway has many solid precipitation events often accompanied by high wind speeds where the current ...

Using SWAT to simulate streamflow in Huifa River basin with ground and Fengyun precipitation data
High-resolution satellite precipitation products, which can provide a reasonable depiction of the spatial extent of rainfall, have been increasingly used to model hydrological processes. In this study, we introduced important satellite rainfall data – Fengyun (FY) precipitation product, and evaluated the data through streamflow simulation using the Soil and Water Assessment Tool model in ...

ORG Rain Intensity Test by NASA at Wallop Island
Traditionally, rain measurements are made by some form of collecting device. The mechanism by which the rain amount was gauged varied from simple straight-walled containers with a measuring stock to more complicated devices that weigh the amount of rain in a bucket. Like any sensor, each of these collecting-type of rain gauges has advantages and disadvantages. Traditional gauges that collect ...
