CROCUS Lake Breeze (May 7th, 2023)#
Lake Breeze are winds that blow off of Lake Michigan on shore due to difference in temperature between the lake and the shoreline.
While providing some relief from the heat during the Spring/Summer, these winds also can trap pollutants (in gas and particle form) at the surface creating unsafe air quality conditions.
With an unstable atmosphere, these lake breeze circulations can also initiate convection (i.e. vertically building clouds) and produce thunderstorms as was the case on 7 May 2023.

Data Query#
National Weather Service Radar - Romoville, IL (KLOT)#
The National Weather Service Next Generation Radar (NEXRAD) in Romoville, IL provides radar coverage for the Chicago Region, allowing meteorologists to understand potential weather hazards (severe storms).
We show how to query data from this station and create a phase plane indictator (PPI) movie for the events of the user’s desire
This will allow us to investigate meteorological events within the region and compare against our CROCUS Nodes
# Configure the nexrad interface using our time and location
conn = nexradaws.NexradAwsInterface()
scans = conn.get_avail_scans_in_range(START, STOP, RADAR_ID)
print("There are {} scans available between {} and {}\n".format(len(scans), START, STOP))
# Download the files
results = conn.download(scans, templocation)
There are 48 scans available between 2023-05-07 16:00:00+00:00 and 2023-05-07 21:00:00+00:00
