Research Facilities

The members of PEER run major research facilities, some of them unique. Please find below an overview of the facilties which are open to interested researchers.

Environmental Research Aircraft PHWUR

Short description:

Environmental Research Aircraft PHWUR

Major research issues/sites:

  • Measuring atmospheric fluxes of heat, water (evaporation) and greenhouse gases (CO2, CH4)
  • Spatial variability of surface fluxes
  • Boundary layer profiling

Short technical description:

  • Fully certified aircraft (pilot + passenger): range 300-400km, typical altitude for surface fluxes 200ft, ceiling ~6000ft, cruise speed 70knts; payload ~50kg max depending on configuration
  • Equipment: turbulence probe, thermocouple, IRGA H2O/CO2/CH4, PAR and net radiometers, infrared thermometer, laser altimeter, IGPS, DAC computer
  • Processing and mapping software

Options and conditions for visiting scientists:

Available in joint projects, otherwise available subject to time constraints and operational cost funding

Unit Cost of use and principles of costing:

  • Operational costs around €400 per flight hour (fuel, pilot, insurance, airport taxes, etc)
  • Scientific/technical preparation planning: €1000 per day, # hrs depending on complexity of operations, special permits, etc
  • Post processing: €800 per day, # hrs depending on complexity of dataset (minimum about 4hrs per flying hour)

centre running the infrastructure:

WENR - Wageningen Environmental Research

type of facility:

Experimental facilities , Laboratory / high-end instrument
