Remote Alpine Weather Station Upgrade Remote Alpine Weather Station Upgrade <div class="ExternalClass4983741817AE42B282576AA2FBFEEA26"> <p>The new tower is much stronger than the old one and designed to better resist the phenomenon of snow ‘glide’ that occurs when deep, dense snow packs actually shift, potentially causing damage to fixed structures. This replacement project was challenging to coordinate and complete due to ever-changing weather conditions as well as the isolated nature of the work site. The tower upgrade and recalibration of the instrumentation will ensure that accurate meteorological data will continue to be collected. Instrumentation was removed from the old tower and later reinstalled and recalibrated on the new one. </p> <p>The meteorological information that Metro Vancouver collects includes temperature, humidity, wind speed and direction, and precipitation. This weather information is helpful in determining wildfire risk in the summer. Snow information for depth and density also forms the basis for determining the amount of water being stored within the watershed as snow, and contributes to the assessment of water availability for the drier summer season ahead. This facilitates decision-making around water management, consumption and conservation. </p> <p>Metro Vancouver’s other two remote weather stations are located at Palisade Lake in Capilano watershed and Disappointment Lake in Coquitlam watershed. The three stations are located high in the north shore mountains. </p></div>|#2fa185f6-6c4a-4b0c-8689-5bb359637cd2;L0|#02fa185f6-6c4a-4b0c-8689-5bb359637cd2|Issue 3;GTSet|#d14ffe11-45dc-48fb-8684-ff109cf15a74<div class="ExternalClassDD6F060C2FC94450A449840E923B307F"> <p>Metro Vancouver has three remote weather stations that provide vital real-time weather data that are essential to a number of water services programs. Recently, a team of Metro Vancouver staff travelled by helicopter to the Orchid Lake station to replace a 7.6-metre tower at almost 1200 metres above sea level.</p> <p>The tower houses the weather station and after 14 years of harsh winter conditions - when the tower was sometimes completely covered in snow - the metal structure was in a weakened and unsafe condition. </p></div>
