Two weeks ago, I talked about an introduction to radar and how it works on a basic level. This time, we are looking into radar reflectivity specifically, the most popular product of weather radar.

After Monday’s winter weather, areas around the Peninsulas and the western Southside accumulated three or more inches of snow. And that snow slightly affected high temperatures this week. Snow has a ...

Observations confirmed that dark coating can reduce satellite reflectivity by half. There are concerns that numerous artificial satellites in orbit could impair astronomical observations, but these ...

That change in reflectivity, known as albedo, is not a distant abstraction. It is emerging in the same decades that have already delivered record heat, stronger heat waves and disrupted seasons, and ...

A new analysis of the Northern Hemisphere’s “albedo feedback” over a 30-year period concludes that the region’s loss of reflectivity due to snow and sea ice decline is more than double what ...
