New study published in AMTD: Adaptive Baseline Finder (ABF), a statistical data selection strategy to identify atmospheric CO2 baseline levels and its application to European elevated mountain stations
A group of scientists working in German, Swiss and Spanish institutions has published a study in the scientific review Atmospheric Measurement Techniques Discussions. A researcher from Izaña Atmospheric Research Center has participated in this study. Critical data selection is essential for determining representative baseline (background or not influenced by local emissions) levels of atmospheric trace gas measurements even at remote measuring sites. Different data selection techniques have been used around the world which could More...

Time-lapse of the local storm that developed in part of the Teide National Park on August 25, 2017.
  The effect of daytime heating on the Cañadas del Teide, in an environment of thermal instability by warm African advection at low levels, triggered the convective development of high base clouds that grow vertically until they develop anvil-shaped cumulus producing precipitation and some lightening storm in a small area of ​​the Teide National Park, next to the volcano. Some thermal instability in medium levels is observed by the warm advection at mid-altitude, without dynamic forcing nor much humidity available causing a high More...

19th WMO/IAEA Meeting on Carbon Dioxide, Other Greenhouse Gases, and Related Measurement Techniques (Dubendorf, Switzerland, August 27-31, 2017)
  From 27 till 31 August 2017, the “19th WMO/IAEA Meeting on Carbon Dioxide, Other Greenhouse Gases, and Related Measurement Techniques (GGMT-2017)” was held in Dubendorf (Switzerland). The institution that hosted this meeting was EMPA, which acts as the World Calibration Centre (WCC) for CH4, CO2, CO and tropospheric O3, cooperates closely with the WCC for N2O, and performs scientific audits to the Global GAW stations (for example Izaña, where the last scientific audit for greenhouse gases, carbon monoxide and tropospheric ozone More...

The study titled “The pulsating nature of large-scale Saharan dust transport as a result of interplays between mid-latitude Rossby waves and the North African Dipole Intensity” has just been published in Atmospheric Environment.
The main objective of this study was to explain the atmospheric processes behind the intra-seasonal variations of dust outflows towards the Mediterranean and the subtropical North Atlantic Ocean. Daily and monthly data of MODIS Aerosol Optical Depth MODIS aerosols, NCEP / NCAR reanalysis, ECMWF reanalysis, and MACC reanalysis (today Copernicus CAMS) have been used in this study. To achieve this goal, we have used  the North African Dipole Intensity (NAFDI) concept recently introduced by Rodríguez et al. (2015), which is defined as the More...

Assessment of nocturnal Aerosol Optical Depth from lunar photometry at Izaña high mountain Observatory
  Moon photometry has arisen as a useful tool for a daily and continuous aerosol monitoring, especially at high latitudes. A precise Moon irradiance model is mandatory in lunar photometry in order to take the continuous change of Moon’s brightness over the cycle into account. So far, the RObotic Lunar Observatory (ROLO) model, published in 2005, is considered an essential tool for Moon photometry. However, very limited studies exist in the literature focused on the application of this model to night-time data as well as to study the More...

Calibration at Izaña station of 100 TENUM Calitoo sun-photometers involved in the GLOBE scientific-educational program
    From 26 June to 3 July 2017, one hundred Calitoo sun-photometers have been calibrated at Izaña station (IARC-AEMET). This small educational sun-photometer has been manufactured by TENUM and developed under the scientific and technical supervision of Dr. Phillipe Goloub and Eng. Luc Blarel from the Laboratoire d'Optique Atmosphérique (LOA; CNRS-University of Lille). Calitoos are involved in the Global Learning and Observations to Benefit the Environment (GLOBE) program, which is a worldwide hands-on, primary and secondary More...
