BACKGROUND

This web page provides near real-time imagery for New Mexico only.  Other regions are available here.

Estimates of total atmospheric column ozone are based on retrievals in clear sky regions using GOES sounder data from the Cooperative Institute of Meteorological Satellite Studies. Retrievals are available hourly with a maximum resolution of approximately 10x10 km.

Radar data are from a 1-km resolution national mosiac of Hybrid Scan Reflectivity produced at the NOAA/NSSL by V. Lakshmanan.

Overshooting tops are based on an experimental algorithm using 1-km visible GOES satellite data developed by V. Lakshmanan and R. Rabin.  The algorithm uses estimated albedo (visible brightness normalized by the cosine of solar elevation) and spatial contrast due to shadowing in order to identify candidate signatures of overshooting cumulus tops.

Thermal Couplets are anomalous cold/warm signatures on storm tops. These signatures can be manifestations of strong updrafts (overshoot) and sinking motion (downwind of updraft) at the storm top. The algorithm was developed by John Moses of NASA Goddard.

Source Data from the Lightning Mapping Array will be added when it becomes available.

Interactive animations use a Flash applet under development by Tom Whittaker of the Space Science and Engineering Center  SSEC, University of Wisconsin-Madison.
