| Zusammenfassung |
| The Climate Research Facility of the US Department of Energy's Atmospheric
Radiation Measurement (ARM) Program operates a network of ground-based
microwave radiometers. Data and retrievals from these instruments have been
available to the scientific community for almost 20 yr. In the past five
years the network has expanded to include a total of 22 microwave
radiometers deployed in various locations around the world. The new
instruments cover a frequency range between 22 and 197 GHz and are
consistently and automatically calibrated. The latest addition to the network
is a new generation of three-channel radiometers, currently in the early stage
of deployment at all ARM sites. The network has been specifically designed to
achieve increased accuracy in the retrieval of precipitable water vapor (PWV)
and cloud liquid water path (LWP) with the long-term goal of providing the
scientific community with reliable, calibrated radiometric data and
retrievals of important geophysical quantities with well-characterized
uncertainties. The radiometers provide high-quality, continuous datasets that
can be utilized in a wealth of applications and scientific studies. This
paper presents an overview of the microwave instrumentation, calibration
procedures, data, and retrievals that are available for download from the ARM
data archive. |
