LWP Radiometers
(LWP, LWP-U90, LWP-U72+82, LWP-90-150)
 |  |  |
These radiometers are used for the remote sensing of integrated water vapor (IWV) and Liquid Water Path (LWP). Both quantities give column-integrated (total) values rather than vertically resolved profiles.
Applications:
- Liquid Water Path (LWP) measurements
- Integrated Water Vapour (IWV) measurements
- Attenuation monitoring
- Beacon experiments
- Cloud observations
- Climate monitoring
- Satellite tracking
Models:
The RPG-LWP-XXX series of liquid water path radiometers is meant for measurements of total water vapour (IWV, integrated water vapour) and total cloud water (LWP, liquid water path).
Higher sensitivity to low-density (thin) clouds can be achieved by upgrading the standard LWP radiometer with higher frequencies.
Atmospheric attenuation measurements (e.g., for beacon experiments) can be performed.
| Model | Frequencies | Applications |
|---|---|---|
| LWP | 23.8 & 31.4 GHz | Standard two-channel radiometer for estimation of IWV and LWP |
| LWP-U90 | 23.8, 31.4, 90 GHz | Improved sensitivity to thin clouds |
| LWP-U72-82 | 23.8, 31.4, 72.5, 82.5 GHz | Improved sensitivity to thin clouds, |
