Sierra Nevada Snowpack Comparison 2014 - 2015

A series of atmospheric rivers in December 2014 brought much needed precipitation to a drought-stricken California. The result is a visibly greener land cover in early 2015 compared to the same time the previous year, as seen in these Suomi NPP satellite images. The state, however, is still in an extreme drought, having received very little rain or snow since. This lack of precipitation, along with warmer than normal temperatures, has resulted in much lower snowpack in the Sierra Nevada Mountains between the two years. Analysis by NOAA confirms that the extent and depth of the snowpack is much less in 2015 compared to 2014 along with higher snowpack temperatures (i.e, melting).
