GRUAN certification for RS-11G GRUAN Data Product Version 1 (RS-11G-GDP.1)

The RS-11G GRUAN Data Product Version 1 (RS-11G-GDP.1) has been certified by GRUAN.

The RS-11G GRUAN Data Product Version 1 (RS-11G-GDP.1) has been certified by GRUAN. We congratulate the Meisei-/ JMA-team with this proud achievement.

The GRUAN data processing for the Meisei RS-11G radiosonde was developed to meet the criteria for reference measurements. These criteria stipulate the collection of metadata, the use of well-documented correction algorithms, and estimates of the measurement uncertainty. An important and novel aspect of the GRUAN processing is that the uncertainty estimates are vertically resolved. The algorithms that are applied in version 1 of the GRUAN processing to correct for systematic errors in radiosonde measurements of pressure, temperature, humidity, and wind, as well as how the uncertainties related to these error sources are derived. The RS-11G was regularly launched at Tateno (TAT) between July 2013 and September 2017 and during January to February, 2018. It has also been regularly launched at Syowa (SYO) since March 20th, 2018.
