title: [Frequency of microclimatic measurements in ecosystem analysis].
abstract: In ecosystem analysis evaluation of the parameters (average values, extremes, correlations) may show errors if the frequency of measurements is too small. Radiation should be measured every 7 minutes in the open, in the vegetation layer even every 2 minutes as computer analysis of characteristic courses of irradiation has shown. Further reduction of the frequency of measurements can be obtained using electrical integrators.
