del Norte air quality monitoring network is deployed throughout the
three regional jurisdictions. The network consists of both continuous
monitors and non-continuous samplers.
Ambient Monitoring Stations (CAMS) contain equipment which observes
both gases and particulate matter. Gas monitors measure ambient concentrations
of ozone, carbon monoxide, and oxides of nitrogen. Particulate matter
is measured in two fractions - PM10 (particles between 2.5
microns and 10 microns in aerodynamic diameter) and PM2.5
(particles with an aerodynamic diameter of 2.5 microns or less. Continuous
ambient particulate matter monitoring is conducted using a TEOM (tapered
element oscillating microbalance) device. El Paso operates a PAMS (photochemical
assessment monitoring station). It measures 52 organic gases associated
with ozone formation.
monitoring also observes both gases and particulate matter. Non-continuos
gas monitoring is conducted using summa canisters which are 5-liter
stainless steel tanks. On a specified schedule, air samples are pull
into the summa canisters for analysis in TCEQ laboratories.
particle sampling is conducted using either PM10 Hi-Volume
samplers located in all three jurisdictions and PM2.5 samplers
located in Doña Ana County. El Paso operated 8 non-continuous PM2.5
samplers for 4 years to determine compliance with the PM2.5
standard. The samplers were removed from the field and deployed elsewhere in Texas
once it was determined El Paso complied with the PM2.5 standard.

you to continuous monitoring networks operated by all 3 jurisdictions.
It should be noted the Cd. Juarez continuous ambient monitoring network
was integrated into the State of Texas continuous ambient monitoring
network to simplify the acquisition and reporting of data in the Paso
del Norte region.
Current and historical
data are obtained from both the Texas-Cd. Juarez and the NMED websites.
