STEM Professionals' Blog


The GLOBE International STEM professionals Network (GISN) Blog is an online collaborative effort where scientists associated with GLOBE post their thoughts, comments, and philosophies about a variety of science topics.

GLOBE strongly encourages positive and productive discussions to further advance the scientific understanding of all involved with The GLOBE Program.




By Olawale Oluwafemi (Femi), (Nigerian Space Agency) and DeStaerke Danielle (CNES) The primary objective of every research project is not only about what you discover but also how do you communicate your discoveries to the interested audience. Delivering either a poster or oral presentation at a scientific meeting is not an easy task, but my passionate friend Danielle and I will present tips that will assist GLOBE Students and Teachers to deliver good scientific presentations.  Plate 1: Femi delivering poster presentation during GLOBE Annual Meeting at Estes Park,...

Observations of daily precipitation have been a part of GLOBE from the beginning. At the start, GLOBE’s participation model was that schools would take measurement following all of the original 17 protocols. Atmosphere temperature, precipitation, cloud, and soil moisture measurements were to be collected daily at a site easily accessible to the school. A permanent installation of an instrument shelter containing a max/min thermometer mounted to a post along with a rain gauge was the expected norm with other measurements taken nearby. Daily temperature and precipitation measurements were...

From the start, the measurement of daily maximum and minimum air temperature within one hour of local solar noon has been a key GLOBE protocol. The low cost approach was to use a U-tube thermometer housed in a wooden instrument shelter facing away from the equator. The U-shaped tube contained mercury with pins on either side of the mercury. As the air temperature warmed the pin on one side would move while the other pin stayed in place; when the air cooled, the pin on the other side would be pushed up. The pins were held in place by magnetized strips behind the thermometer tube so that...

In most scientific research an important test is whether the results of an experiment can be repeated, typically repeated by another lab and research group. A result that cannot be confirmed in this way is generally viewed as invalid. This is a great test for controlled experiments where virtually identical experimental conditions may be achieved. In Earth science research involving observations of the natural world, experimental conditions cannot be reproduced. For environmental research the standard must switch for repeatable to intercomparable – capable of being compared. Research...

Beste mensen, Het effect van de uitzonderlijk zachte winter op de natuur is ook bij de media niet onopgemerkt gebleven. In de uitzending van het KRO programma Brandpunt op zondag 16 maart komt het onderwerp aan bod. Zie http://gemi.st/KN_1656575 . Het item begint op 23:20. Verder zat ik op zondag 9 maart in het programma Jinek op Zondag. Dit is terug te zien op http://gemi.st/KN_1656819 . Tenslotte zat ik op woensdag 19 maart in het EO-programma 'Melk en Honing'. De uitzending is terug te bekijken op  http://gemi.st/EO_101212300 . Vriendelijke groeten, Arnold
