Due to the curvature of the Earth, the height of a radar beam, in relation to the ground, increases as it travels further from the radar. When the radar is pointed down near the ground (a low elevation angle), the beam starts off near the ground but then its height above the ground slowly...

DPQPE product: DPQPE stands for: Dual Polarization Quantitative Precipitation Estimation. The DPQPE product is available only for S-Band radars. It is a two-dimensional representation of the precipitation rate estimated by the lowest sweep of the radar (elevation angle of 0.4 degrees for the...

This product shows the rain accumulation, in mm, over the last 24 hour period based on PRECIP-ET and DPQPE. For PRECIP-ET, this product is available every 10 minutes for C-Band radars and every 6 minutes for S-Band radars. For DPQPE, this product is available every 6 minutes.

The PRECIP-ET (PRECIPET on images) is an extension of the PRECIP product (hence the use of ET in the product name). Compared to the previous PRECIP product, the PRECIP-ET performs a suite of additional quality control (QC) tests and tracks issues better. For example, Doppler filters might be...

The Precipitation Occurrence Sensor System (POSS) is a small X-band 10.525 GHz continuous-wave bi-static vertically pointing Doppler radar. The system reports precipitation occurrence, type and intensity of precipitation at 1-min temporal resolution. Raw measurements are 960 samples per minute....

In 2015 as part of the Canadian Artic Weather Science (CAWS) project, Environment and Climate Change Canada (ECCC) established an enhanced monitoring reference site at Iqaluit, Nunavut (CYFB, 63°45N, 68°33W) in the eastern Canadian Arctic. The site was strategically selected at the loci of...

The Whitehorse enhanced meteorological site is located at Erik Nielsen Whitehorse International Airport (CYXY, 60°43N, 135°04W). This scientific observation site aims to provide a better understanding of the region’s weather conditions to help improve local weather forecasts across the Canadian...

Mesoscale boundaries have an important influence on mesoscale weather. They can trigger, enhance or inhibit convections and severe weather. They are also indicators of shifts in wind speed and direction, temperature and relative humidity, and can affect air quality and heat indices. Around the...

Data collected between 1989 and 2007. Riometers passively monitor radio noise from extrasolar sources and have been shown to be an effective way to monitor high-energy electron populations in the region of space around the Earth. Data is in text (.txt) format. .tar.gz files are compressed...
