Status of Automatic Weather Stations

• 74 AWSs working with near real time availability
  of data on the Internet
• Highly probable that for the NAME the number will
  climb to 84
• Measurements (averages or accumulations) at 10
  minute intervals
• GOES telemetry every 3 hours
• Publication on Internet time lag between 15 and
  75 minutes, depending on the actual time of
  transmission

What other AWSs could be available?25 AWSs
operated by SEMAR (mexican military Navy)
(only 22 on this map) (other 39 non-telemetric)
(telemetry through the Solidaridad satellite)
15
What other AWSs could be available?10 AWSs
operated by GASIR-CNA (Surface Hydrology River
Engineering)
(GOES telemetry)
16
What other AWSs could be available?44 AWSs
operated by CILA (International Boundary and
Water Commission-Mexican side)
(GOES telemetry)
17
What other AWSs could be available?Several
agromet networks (for example 2 in the state of
Sonora)
7 Agro-AWSs near Hermosillo
(usually short range telemetric)
10 Agro-AWSs near Caborca
14.7 km
16.4 km

Meteorological Observatories

• 83 surface synoptic stations
• Nominally measurements every hour, transmission
  every 3 hours (8/day)
• Pen and paper recording instruments
• Reality
• Staff of 7 required for full operation
• On average staffed by 4.3 observers
• Down from 5.1 a few months ago
• Can still go down from now to summer-2004
• Data available in near real time from WMO-GTS
  (for example WAFS station)
