Step Into the China Meteorological Administration's Research Center

Few people from Europe and North America are fortunate enough to visit the China Meteorological Administration (CMA). Two of them are Clive Lee and Ruud Ringoir - Business Managers at OTT HydroMet's brand Kipp & Zonen - who accepted an invitation to visit the CMA headquarters in Beijing and its research center and BSRN station situated in Xilinhot, Inner Mongolia.

The trip took place in 2012 after the company’s International Sales Meeting in Penang, Malaysia, having been organized by Joe Zhou, General Manager of its Chinese distributor Beijing Techno Solutions Ltd. A rare occasion to get first-hand impressions from far east partners.

CMA works with a diverse array of products from OTT HydroMet's brand Kipp & Zonen, prompting the company to request an in-person visit to explore a range of topics, including international standards, calibration, specifications and a series of instrument-specific questions.

Presentations were given on Kipp & Zonen and its products in Bejing on Sunday 14th of November. These talks also covered a range of individual instruments and their calibrations.

The day in Beijing was a stark contrast to the +30 °C monsoon conditions that the team had experienced in Penang, with blue skies, light snow and temperatures around freezing.

The day after the presentations, the team from Kipp & Zonen traveled along with Joe Zhou and three CMA employees to visit CMA’s meteorological center in Xilinhot, Inner Mongolia. This visit involves a range of productive and informative discussions around installation, maintenance, quality control and data management.

CMA’s primary measurement station is situated a 1-hour drive from the city. Its flat tundra location, uniform landscape and the availability of a 360-degree clear view make it an ideal location for acquiring radiation measurements.

Temperatures between -20 °C and -25 °C with strong winds pose some challenges to instruments inspections, however.

The station makes use of a 2AP sun tracker with shading ball assembly to measure the direct radiation. This is fitted with a CHP 1 pyrheliometer. Ventilated CMP 21 pyranometers are employed in global and diffuse radiation measurement.

The station also features a ventilated CGR 4, used to measure downwards infrared radiation, and a short mast with a UVS-AB-T and a PAR Lite used to measure UVA, UVB and Photosynthetically Active Radiation.

A 30-meter tall mast with downwards facing CMP 21 and CGR 4 is used to measure reflected radiation and upwards infrared. This is situated a suitable distance away to avoid shadows. Measuring all four net radiation components also allows albedo to be calculated.

A fully instrumented 200-meter high meteorological tower is in operation, including a CNR 1 net radiometer. The addition of ventilation units to the downwards facing radiometers will allow the site to fully adhere to the requirements for an Extended Baseline Surface Radiation Network Station (BSRN).

A building is used to collect and analyze the data based a few hundred meters from the measurement site.

This was set up by Beijing Techno Solutions, with this company completing the installation, providing the data loggers and developing specialized software to graphically display all required parameters on a large LCD screen.
