CDER strengthens its network of climate observation

Prof. Noureddine Yassaa, Director of the EPST CDER. Focal Point of the GIEC of Algeria

Conscious of the environmental interests that a network of climatic observation could convey, the CDER marks its will and its total availability in the observation of the climate and its changes, through the strengthening of the network CHEMS.

Indeed, within the CDER’s research works, for a number of years, an observation network named CHEMS which means sun, is available.

CHEMS is a nework of measurement of solar radiation and meteorological parameters, the first station of which is installed on the heights of the capital, on the CDER headquaters at Bouzareah in 345 meters above sea level. This measuring station, continuously, the parameters occurring in the functioning of the systems with renewable energies, particularly the radiometric and wind parameters. The station is equipped with several pyranometers, with a pyrheliometer and with a Sun tracker, which measure various components of the sun rays and the duration of sunshine. The speed and the wind direction are measured, on the other hand, by means of a wind gauge with a wind vane with ultrasounds. The station is also equipped with meteorological sensors for the measure of the temperature, moisture, rainfall volume and atmospheric pressure.

The datas measured by CHEMS, and available, in real time (update each 5 minutes), on the web site of the Algerian Portal for Renewable Energies

The CHEMS network has been strengthen by the acquisition of Aethalometer which is a specific equipment in the measure of the atmospheric sprays and more particularly the follow-up of the carbon soot concentrations or " black carbon ". These real time measures allow not only the determination of the contents of this particular pollutant and their diurnal, night, daily, annual and multiannual evolutions but also the identification of their sources towards the atmosphere. This particular family of the atmospheric sprays is classified by the Intergovernmental Group of Experts on the Evolution of the Climate ( GIEC) in the directory of pollutants contributing to the global warming.

As such, the fifth evaluation report of the GIEC has just been finished with the publication of the Summary report in this November with conclusions more alarming than the previous report of 2007. This report is more certain than the previous. It indicates, that with a probability superior to 95 % " extremely likely, more than 95 % of chances ", the accumulation of greenhouse gases ( GES ) due to human activities are at the origin of the rise of the ground temperature collected since the middle of the XXth century. According to this evaluation, " the atmosphere and the oceans warmed themselves, the quantity of snow and ice decreased, the sea level rose and the concentration of carbon dioxide increased until an unprecedented level for 800 000 years. " What about the increasing by the global warming of the desertification, the degradation of grounds, phenomena of drought more frequent, desert dusts which affect the air quality and the health of the populations among other phenomena that the report of the GIEC did not dedicate specific studies.

The lack of observation in the countries of the South in particular in the African continent was many times pointed in the report of the GIEC leading gaps of knowledge and a bigger uncertainty on the impact of climate change on a local scale and regional. Efforts of the international community must be centered in the implementation and the strengthening of the observations in the African continent and in the capacity building through the training and the transfer of technology and knowledge so that the African scientists can contribute actively in the elaboration of the next report of the GIEC, fill the existing gaps in the fifth report and insure a well-balanced and fair geographic coverage of the evaluation studies.

To deal with the problem of the climate change, more than 3000 scientists, high-level political decision-makers of 109 countries, negotiators, media professionals are gathered in Lima Peru, an initiative of the United Nations General Secretary Ban Ki Moon, within the Works of the 20th Conference of the Parties to the Framework Convention of United Nations on climate change ( COP20).

Algeria participates actively in this meeting with a strong multisectorial delegation, led by the Secretary of the Country Planning and the Environment, Delilah Boudjemaa.

The works of the COP20 should result in the elaboration of a new climatic policy, binding and applicable to all the parts for period pre-2020, that must be approved by the parties during the next COP of Paris in 2015. The negotiations look very difficult, especially as regards the platform of Durban ( ADP) which should not handle only with the reduction of greenhouse gas emissions, but on all the elements of the 1CP17 decision (Kyoto protocol), which must be approached in a well-balanced and integrated way. It is among others the adaptation to the climate change which remains the main concern for a big part of developing countries, and also means of implementation (financing, technology transfer and the capacity-building).

Algeria joins in the principles of the Agreement and the historic responsibility of the developed countries which have to be the leaders by meeting their commitments on the question of the reduction of the greenhouse gases emissions ( GES). The contribution of developing countries to the international effort must be determined to the national level by taking into account circumstances and national capacities in adequacy with the principle of the common responsibilities but differentiated. The COP of Lima coincided with the commitment calculated by the European Union to reduce their emission of the GES by the year 2030 and a commitment still not calculated by the United States and by China to reduce their GES emissions.
