About the Authors
Jessica D. Lundquist• Professor of Civil and Environmental Engineering,
University of Washington• Research focuses on spatial patterns of snow and weather
in the mountains and how those patterns are likely to affect stream flow and water resources in a changing climate.

The Problem(s)
Few measurements exist
FACTORS: Severe terrain Remote area Limited access Area of study is in Protected areas
SOLUTION:
A monitoring system that of low maintenance, low powered and unobtrusive
The paper is addressing the following problems.
OverviewNaturally most of the data gathered for studies are from areas accessible and mostly in the less elevated area.
Overview
Test Basins: Merced River and Tuolumne River in Yosemite national Park (Highway 120)
Elevation: 1200 to 3700 m
Why Merced River?
-because it has a long daily record (1916-present)

ReviewCommentary and Recommendation
The Novelty
What is new?
The application of sensor network in meteorological and hydrological study of change in snowmelt runoff in Yosemite National Park. However we cannot say that there is novelty claimed by the authors.
Novelty applies to:
The device used so it can be suitable to the requirement the authors specifications. (Low maintenance, low-powered, unobtrusive, the circuit design. etc.)

Strength and Weaknesses
Plus The implementation of the prototype of sensor network
in this study opens to wide area of researches and better numerical models for the climate change .
CON The authors did not include details about the type of
sensor or any technicality about it. The title is broad. The study did not clearly state the method of how they
collected the data using the data logger. It is more focus on the meteorological and hydrological
side than of the sensor network. Some figures as published are not coherent with his
discussion. No detail about the network and how it was
implemented and all the technicality in engineering side.
Recommendations
It could have been better if the sensor network developer, Douglas Alden, co-authored with this article to have support the science.
Update
Thank you!Queries.
