Climate Change Research Facility

What will tomorrow’s world be like in light of elevated carbon dioxide and temperature? What will society need in ten or twenty years’ time? Addressing such issues is essential to ensure timely identification of trends and future markets. That’s what Saveer does.

This facility is highly appreciated by a number of Scientists from our Country’s renowned Institutes.

We specialize in establishing

  • Free-Air Carbon Dioxide Enrichment (FACE)
  • Free-Air Temperature Enrichment (FATE) for climate change studies
  • Carbon Dioxide Temperature Gradient Chamber (CTGC)
  • (Free Air Ozone Enrichment) FAOE Facility

Free-Air Carbon Dioxide Enrichment (FACE)

  • Environmental research facilities to conduct controlled Temperature, CO2 enrichment, and other manipulative experiments on intact ecosystems under natural environmental conditions.
  • A number of CO2 enrichment technologies have been developed for crop response studies in the presence of CO2.
  • Free-air carbon dioxide enrichment (FACE) technology provide a unique opportunity to examine the effects on plant growth at elevated CO2 and other environmental conditions without any direct perturbation of microclimate.
  • With current Free-air carbon dioxide enrichment (FACE) technology, CO2 enriched air is injected around the perimeter of circular plots and natural wind disperses the CO2 across the experimental area.
  • There are no walls interfering with incident radiation and no artificial constraints on rooting depth.

Free-Air Temperature Enrichment (FATE)

  • Free Air Temperature Enrichment (FATE) technology has design for induced artificially canopy temperature in open field conditions without any use of enclosures.
  • The FATE technology will be connected with Temperature and CO2 controlling and monitoring system for effective control of temperature and CO2 concentration.
  • Control system can measure every second the data from weather station (wind speed and direction) along with CO2 concentration.
  • Based on these inputs, control system, through a specially developed PID algorithm, controlled flow rate of CO2 with the help of PID controller valve.

(Free Air Ozone Enrichment) FAOE Facility

  • Tropospheric ozone (O3) is one of the serious air pollutants that have negative effects on both 3 plants and animals. Results from most of the field experiments have shown conclusively that agricultural crops and trees are adversely affected by O3.
  • Ozone effects on plants are initiated in leaves when the gas enters through the stomata and disrupts cellular processes, resulting in lowering of the rate of photosynthesis, suppression of growth and yield of many crops.
  • Tropospheric ozone may cause reduced resistance to fungi, bacteria, viruses, and insects, reducing growth and inhibiting yield and reproduction.
  • Free air ozone enrichment Facility as to permit the modification of the ambient air's composition while reducing the changes of other environmental conditions to a minimum.
  • FAOE is state of the art; free-air trace gas enrichment systems provide the best solution for open field research of ozone effect on plants.
  • Free Air Ozone enrichment technology processes information from various sensors inside experimental plots to regulate O concentration 3 increases through series of control feedback loops.
  • A computer control system uses information on wind direction and speed and ozone concentration at the middle point of the ring to control the gas release. This information is then transmitted to the central computer for real time performance analysis and data archival.


  • Temperature monitoring in experimental plot
  • Crop canopy temperature
  • CO concentration 2
  • Ozone concentration
  • Wind velocity & direction

  • Light

Features of FACE, FATE & CTGC:

  • Provide a unique opportunity to examine the effects on plant growth at elevated CO2 and other environmental conditions without any direct perturbation of microclimate.
  • Collectively constitute a distributed user facility across different geographic ecosystems.
  • Allow long-term, continuous measurements on ecological processes and responses.
  • For maintaining elevated crop canopy temperature of ambient + 3°C ± 0.5°C with special infrared heaters of 230V.
  • Pressurized and refrigerated CO2 tank to maintain the required pressure with safety certificates from authorized agencies.
  • CO2 monitoring by NDIR micro processor.
  • Data storage and backup in a readily accessible format.
