Environmental Observations

  • Aerosols & atmosphere

NEO researchers, in collaboration with National Hellenic Meteorological Service, have established an Atmospheric Observation Station at Methoni, a coastal site at SW Greece (36° 49' 32'' N, 21° 42' 17'' E, 50 m a.s.l.), in order to track climate change signals and air pollution. It is an important part of a European Network and fills the gap of missing data from this part of Europe. The role of the station is to maintain long term monitoring of aerosol physical, chemical and optical properties, in an attempt to shed light on factors controlling their levels and variability as well as to discriminate the relevant contribution from long range transport versus local sources, with emphasis on the role of biomass burning (branches burn - oil trees harvest, domestic heating). 

Some of the instruments that operating at Methoni's station are:

• Nephelometer 
• Aethalometer 
• Custom made DMPS (Sweden SU) and an Aerodynamic Particle Sizer (APS-3321, TSI)
• Particulates analyzers for real-time continuous measurements of PM10
• Gas analyzers: O3, CO

  • Wetlands and groundwater resources

To better understand the processes (natural and anthropogenic) affecting the wetland, apart from field observations (e.g. birds, reptiles), NEO has established a network of sensors for monitoring basic water physical-chemical parameters (see map below). The network, consisting of a meteorological station and several water monitoring stations, was first installed in 2016 (NEONEA20), and it will soon be updated (Autumn 2020) to allow the monitoring of the below parameters (with italics measurements since 2016):

Hydroclimate parameters

  • Electrical conductivity

  • Temperature

  • Depth

  • ReDox potential, pH

  • Dissolved oxygen


  • Precipitation

  • Temperature

  • Soil radiation

  • Wind speed & direction

The new network will also include groundwater monitoring stations equipped with CTD (Conductivity-Temperature-Depth) sensors and piezometers (see also map).
