      abstract     = {[1] In this work the instrumentation and characterization
                      of a filterradiometer suitable for field measurements of O-3
                      --> O(D-1) photolysis frequencies, j((OD)-D-1), is
                      described. A nonlinear calibration function considering
                      ozone column and solar zenith angle is derived as well as a
                      procedure utilizing an irradiance standard as an absolute
                      reference. The measurement concept is tested by a field
                      comparison with a spectroradiometer. Based solely on
                      laboratory characterizations and simulated solar actinic
                      flux spectra, a systematic deviation of $4\%$ is obtained
                      with a standard deviation of $3\%$ at solar zenith angles
                      below 70degrees. The standard deviation rises to $8\%$ at
                      solar zenith angles in the range 70degrees - 85degrees. The
                      systematic difference is within the accuracy of the applied
                      radiometric calibrations while the standard deviation is
                      mainly caused by insufficient synchronization of the
                      different measurement techniques under variable field
                      conditions. In addition, the relative temperature dependence
                      of j((OD)-D-1) as a function of solar zenith angle and ozone
                      column is derived which is applicable to any ground-based
                      j((OD)-D-1) measurement.},
