297 | <p>The new disaggregation method for precipitation fields produces two additional precipitation fields for each time step and precipitation type. They serve as sub-grid points in the original time interval. For details of the method see <a class="reference internal" href="disagg.html"><span class="doc">Disaggregation of Flux Data</span></a> ??????????????????. |
---|
298 | The two additional fields are marked with the <code class="docutils literal notranslate"><span class="pre">step</span></code> parameter in the Grib messages and are set to “1” and “2” for sub-grid point 1 and 2 respectively. |
