Remember, the data used to produce these maps are "modeled" utilizing actual observations. Tim indicated that the Northway from Burlington VT and Plattsburgh NY and up to the Canadian border is snow-free in the model. There are also a few snow-free patches in central Massachusetts and New Hampshire. According to Tim, "...there seemed to be a halo of a few open pixels around Lake Champlain and along the Atlantic coastline. There may be snow on the beaches, but the effects of the warm water and downscaling the derived temperatures would extend inland a bit." Also, when the maps are produced masks are used to delineate land and water. These masks are more detailed than the 1 km square blocks for snow cover, so the resolution differences could contribute to that 0.8%.Steve Hilberghttps://www.blogger.com/profile/08641354875013009133noreply@blogger.comtag:blogger.com,1999:blog-3915442507015152354.post-47582275217874160292015-02-06T08:04:06.310-07:002015-02-06T08:04:06.310-07:00Pete, that's a good question, Clearly the map ...Pete, that's a good question, Clearly the map shows complete snow cover. I suspect it has something to do with the assimilation model NOHRSC uses. I'll see what I can find out.Steve Hilberghttps://www.blogger.com/profile/08641354875013009133noreply@blogger.comtag:blogger.com,1999:blog-3915442507015152354.post-56628988526660360992015-02-06T06:56:06.761-07:002015-02-06T06:56:06.761-07:00Good work, and I appreciate the extra effort of Mr...Good work, and I appreciate the extra effort of Mr. Tripp. Just wondering, though: Where's the 0.8% of the Northeast sector NOT covered by snow?Pete(r) Doughtyhttps://www.blogger.com/profile/15633213784582033875noreply@blogger.com
