Innsbruck Atmospheric Observatory

An urban–Alpine laboratory
above the city.

The IAO connects long-term observations, high-frequency chemical analysis, micrometeorology, remote sensing and intensive field campaigns.

Why Innsbruck?

City, valley circulation and mountains at one site.

The Inn Valley location makes it possible to investigate urban emissions and chemical transformation under pronounced mountain-wind systems. Several measurement levels connect the urban canopy with the overlying boundary layer.

Long-term data reveal changes over years, while intensive campaigns add targeted instruments and international partners.

Measurement tower

High-frequency observations above the rooftops.

The tower supports inlets, meteorological sensors and turbulence instruments. Fast concentration measurements are combined with three-dimensional wind observations to quantify vertical fluxes.

  • Trace gases and VOCs
  • Aerosol size distributions
  • Wind, heat and moisture
  • Eddy covariance and footprint analysis

Observation domains

Four perspectives on the same atmosphere.

01

Chemical composition

Reactive trace gases, greenhouse gases and volatile organic compounds.

02

Aerosols

Number, size distribution and secondary particle-formation processes.

03

Turbulent exchange

Fluxes of heat, momentum, CO₂ and reactive trace constituents.

04

Remote sensing

Pandora observations connect local measurements with atmospheric columns.

Collaboration & data

A platform for shared measurements.

The IAO can support campaigns, instrument comparisons, method development and joint data analysis. The instrument catalogue and Lab Dashboard will progressively connect status, metadata and quality-controlled products.
