URMA

(URMA= “UnRestricted Mesoscale Analysis”) 


The URMA represents actual temperatures and conditions and is used for model verification.  Since it represents corrected/actual observations, the URMA is is released with a six hour delay to allow for corrected data input.


The URMA is the 6 hour delayed, data-corrected version of the “RTMA” (Real-Time Mesoscale Analysis). The RTMA is available every 15 minutes, as the name suggests, in real time.
