![]() BirdCast, live migration map date and time (most easily accessible from image file name/s). The United States satellite images displayed are infrared (IR) images. To cite live migration map graphics, please use the following syntax:ĭokter, A. Learn About United States Infrared Satellite. The BirdCast project was created by grants from the National Science Foundation and supported by additional grants from Leon Levy Foundation. Rose Postdoctoral Fellowship, and Amazon Web Services. Support for this research came from NASA, Edward W. The migration traffic rate indicates the number of birds per hour that fly across a one kilometer line transect on the earth’s surface oriented perpendicular to the direction of movement of the birds.Ĭornell Lab of Ornithology currently produces these maps. the Rockies) have obstructions that restrict radar coverage, providing the appearance of no migration where migration may be occurring.īrighter colors indicates a higher migration traffic rate (MTR) expressed in units birds/km/hour. ![]() ![]() Note that many radars in mountainous areas (e.g. Green dots represent radar locations for which data are available red dots represent radar locations with no data available. Orange arrows show directions to which birds flew. Areas with lighter colors experienced more intense bird migration. You can even change the map style and radar speed. When present, the red line moving east to west represents the timing of local sunset, the yellow line represents the timing of local sunrise. Choose your main map layer, then add on any additional weather conditions you want. All graphics are relative to the Eastern time zone. During severe weather situations, reflectivity signatures can provide valuable clues as to what threats to expect from a particular cell.Real-time analysis maps show intensities of actual nocturnal bird migration as detected by the US weather surveillance radar network between local sunset to sunrise.Bright reflectivity returns that are stationary and appear during both calm and inclement weather are usually land-based obstructions such as mountains, trees, or especially wind farms (nothing gets electromagnetic signals confused like spinning metal blades!).Historical weather maps ECMWF ERA5 weather maps (from 1950) Historical observations Observations (main network). This is helpful for picking out snow/mix/rain transition zones In all snow situations, dBZ values of 40 indicate 3-4”/hr snowfall rates and whiteout conditions. Central Europe Super HD (MOS) (3 days) new Swiss-MRF (10 days) ICON-D2 (2 days) AROME (2 days). Anything larger than this is usually due to “bright banding” where the radar is seeing the part of the atmosphere where snowflakes are clumping together and melting into raindrops. In cold climates during the winter months, actual dBZ values rarely exceed 40.This is your standard radar data that shows precip or other solid/liquid particles in the atmosphere. The first type of data currently available is reflectivity. We currently have two types of radar data available with plans to add more soon. Use radar data with caution especially if your area of interest is far from the nearest radar location! A lot can happen between 0 and 5,000 feet and therefore the depiction of precipitation given by radar may differ some from what’s actually happening on the ground. Because of this phenomenon, the radar beam will only see precipitation falling through the mid levels of the atmosphere. To see this in action, imagine a circle (earth) with a straight line emanating from some point on the circle if you continue this line out into space, it will gradually get farther and farther from the circle. Because the earth is round and the radar beam is flat, the farther away from the radar tower the beam (energy) travels, the farther removed from the ground becomes. There is a notable constraint to radar data though. Learn About Current Radar (Intellicast) The Current Radar map shows areas of current precipitation. This is the highest resolution radar data available which enables you to see features such as sea breeze or outflow boundaries that standard resolution radar entirely misses. Current Radar (Intellicast) Region: Play Animation. This data is gathered from over a hundred radar towers located across the US.
