mio::ProcDeAccumulate Class Reference

Detailed Description

Convert accumulated values back to instantaneous values.

Some radiation parameters are sometimes provided as accumulated values over a given period (such as ECMWF radiation fields). The value at any given timestep is either the instantaneous value (at the beginning of the accumulation period) or the sum of the instantaneous value and the preceeding values. This can be illustrated as:

  • at time t, the value is x1;
  • at time t+dt, the value is x1+dx1;
  • at time t+2dt, the value is x1+dx1+dx2;
  • at time t+3dt, the value is x2;
  • at time t+4dt, the value is x2+dx2;
  • ...

This filter recomputes the instantaneous values by considering that once a value gets smaller than its preceding values, the end of the accumulation period has been reached, so the value is kept as is and the process starts over again (thus this assumes that they are no negative values).
