2018-12 Compact Air Temperature will be available as of January 2019

by Beheerder on 09 December 2018 20:19

As of January 2019, Datawell will introduce a new meteorological parameter on the Waverider.

 

The newly developed Compact Air Temperature (CAT4) option integrates the HF antenna, flashlight and an air temperature sensor. The air temperature sensor applies a novel concept, which corrects the measured temperature for (solar) radiation and detects adverse effects like evaporation.

 

The CAT4 antenna measures the air temperature at approximately two meters above the sea surface, complementing the wave measurements.

 

The CAT4 option is available on all Waverider buoys, except for the DWR-G4.

The CAT4 antenna is not interchangeable with the HF/Flashlight antenna. Also, to upgrade existing buoys, hardware and firmware updates are required.

More technical information and FAQ will be made available on the Datawell website.

 

When interested in this new option, please contact our sales department (sales@datawell.nl) for availability and pricing.

Many Waveriders we supplied have been equipped with a Superstar GPS receiver. Recently it has come to our attention that the Superstar generates a faulty date in the logger files. The problem can be explained by an unexpected “GPS week rollover”. The internal date obtained from the GPS satellite system is incorrect. Typically the date is set to the year 2096. To convert the incorrect data we are currently developing a software tool. The only solution to this problem however is to replace the Superstar GPS receiver. The Superstar position module must be replaced with the µBlox GPS receiver (DWR-MKIII and WR-SG). The µBlox GPS receiver was introduced in the beginning of 2012.
