RPG-HATPRO

Dual profiler for vertical profiles of atmospheric temperature and humidity (including boundary layer profiling) (standard operating manual)

The HATPRO instrument is a stand-alone system for automated weather-station use under nearly all environmental conditions. Full atmospheric profiles are derived, retrieved data as well as raw data are stored. A variety of retrieval algorithms (custom designed or global standard algorithms) can be selected.

RPG-LHATPRO

Dual profiler for vertical profiles of atmospheric temperature and very low humidity (arctic regions, high altitudes) (standard operating manual)

The LHATPRO instrument is a stand-alone system for automated weather-station use under nearly all environmental conditions with special emphasis on cold and dry environments (arctic/antarctic conditions, as well as high altitudes of 3000 to 6000 meters above sea level). Full atmospheric profiles are derived, retrieved data as well as raw data are stored.

RPG-LWP

Liquid water path radiometer: two channels at 23 GHz and 36 GHz (standard operating manual)

The RPG-LWP instrument is a stand-alone system for automated weather-station use under nearly all environmental conditions.

The total (integrated) amounts of water vapor and liquid water in the vertical column above the radiometer are retrieved from the two-channel brightness temperature mesurements.

A variety of retrieval algorithms (custom designed or global standard algorithms) can be selected.

RPG-LWP-U90

Upgraded LWP radiometer: three channel version (23, 31, 90 GHz) for improved accuracy especially in case of thin clouds (standard operating manual)

This LWP-U90 radiometer is an upgraded version of the above LWP two-channel radiometer. By including a high frequency channel at 90 GHz the sensitivity to thin cloud (small LWP) is significantly improved: Instead of approximately 30 g/m^2 the three channel version has a detection limit of 5 to 10 g/m^2. The three channel version is using the same housing as the standard LWP radiometer. The instrument is a stand-alone system for automated weather-station use under nearly all environmental conditions.

The total (integrated) amounts of water vapor and liquid water in the vertical column above the radiometer are retrieved from the two-channel brightness temperature mesurements.

A variety of retrieval algorithms (custom designed or global standard algorithms) can be selected.

RPG-LWP-90-150

High sensitivity LWP radiometer: two channel version (90 and 150 GHz) for improved accuracy especially in case of thin clouds (standard operating manual)

The LWP-90-150 instrument is a stand-alone system for automated weather-station use under nearly all environmental conditions.

The total (integrated) amount liquid water in the vertical column above the radiometer is retrieved from the two-channel brightness temperature mesurements. There is only very limited information on water vapor (humidity) due to the lack of an water vapor line frequency.

A variety of retrieval algorithms (custom designed or global standard algorithms) can be selected.

RPG-90-DP150

Dual-polarized high sensitivity cloud observing radiometer: 150 GHz dual-polarization plus 90 GHz single polarization (standard operating manual)

The LWP-90-DP150 instrument is a stand-alone system for automated weather-station use under nearly all environmental conditions.

The total (integrated) amount liquid water in the vertical column above the radiometer is retrieved from the two-channel brightness temperature mesurements. There is only very limited information on water vapor (humidity) due to the lack of an water vapor line frequency.

A variety of retrieval algorithms (custom designed or global standard algorithms) can be selected.

RPG-DP-RR/LWP-Rain

Dual polarized multi-channel radiometer (10, 19, 36 GHz) for the observation of thick clouds (high LWP) and rain (operating manual - Dual-Pol./Multi-Channel)

The RPG DP-RR instrument is a stand-alone system for automated weather-station use under nearly all environmental conditions.

With orthogonal polarisation information and brightness temperatures at 6, 10, 19, and 36 GHz this instrument is dedicated to the observation of raining clouds.

Polarization effects on non-spherical hydrometeors can be observed with this kind of instrument.

Soil-Moisture

Surface Observations at 19, 23, 36 and 90 GHz (operating manual - Dual-Pol./Multi-Channel)

The Soil Moisture Observing System is designed for field campaign measurements of surface parameters like soild moisture and vegetation parameters.

MICCY

22 channel meteorological radiometer for cloud process studies

MICCY is specifically designed for cloud cartography and thus requires superior optical resolution, leading to the large 0.95 m Cassegrain system. Similar microwave profilers with less demanding optical resolution can be fabricated in a more compact way with much smaller dimensions. Customized versions available (please contact us). During the EU-funded international measurement campaign CLIWANET this radiometer proved to be state of the art. Details on the scientific background, retrieval algorithms, technical data and related links can be found at the MICCY Homepage.

SST

Astrophysics (observation of solar flares at 212 and 405 GHz)

This radio telescope is located in the Argentinean Andes (Complejo Astronomico El Leoncito (CASLEO), 32 S latitude, 69 W longitude, 2550 m altitude). It is designed to study solar flares at short radio wavelengths with a temporal resolution of 1 ms.
