Comparison studies of helical vs. multi-plate radiation shields

Independent studies have been performed my renowned independent organizations like METEOMET, Royal Belgian Meteorological Institute, Slovak Hydrometeorological Institute, Spanish Meteorological Institute, Woodshole Oceanographic Institution....

 

Data from METEOMET....coming soon.

METEOMET

Results from this study are coming soon. We are waiting for the publishing of the official research paper by the METEOMET researchers. It is scheduled for summer of 2017.

Royal Belgian Meteorological Institute

Results of this year long comparison between a Stevenson Screen and the BARANI helical MeteoShield are being processed and will be released in early August 2017.


Comparison studies of helical vs. multi-plate radiation shields

Independent studies have also been performed my private organizations & companies to compare the helical solar radiation shield to current state of the art multi-plate and the best fan aspirated radiation shields

Davis VP2 fan ventilated radiation shield did not provide a benefit over a Barani MeteoShield.

DAVIS vp2 FAN ASPIRATED RADIATION SHIELD

Comparison was performed by an independent researcher in Italy, concluding that the Davis Fan Aspirated radiation shield provided no benefit over the naturally aspirated helical MeteoShield. In fact, for higher reliability and lower maintenance applications, helical radiation shield wins.

Davis 7714 solar radiation screen has a measurement error of up to 0,8°C versus the Barani MeteoShield.

DAVIS VP2 7714 NATURALLY ASPIRATED RADIATION SCREEN

Another independent researcher from France, confirmed in his study a benefit of 0.8°C from the helical MeteoShield over the Davis 7714 radiation shield. During periods of still air, a larger benefit was recorded.

BARANI MeteoShield offers a 1.3°C benefit over RM Young 9007 multi-plate solar radiation shield.

RM YOUNG 9007 vs. BARANI METEOSHIELD

The professional RM Young 9007 solar screen showed significantly higher solar heating errors than the BARANI MeteoShield and the Davis 7714 shield. Solar heating error of 1.3°C higher than the helical MeteoShield was observed.

Example data from Microstep-MIS comparison study. June 2, 2017, a day with strong solar irradiation >1000W/m2 and calm or very low winds.

microstep-mis intercomparison

Over a year long (April 2016 to June 2017) comparison was performed between 4 solar radiation shields (or radiation screens in the UK).

  • BARANI MeteoShield
  • Rotronic Fan Ventilated RS12T
  • Vaisala DRT503A
  • Stevenson Screen

This study started in the spring of 2017 and is in progress. We will update any information here as it becomes available.
