QC2d-4 Statistics control Accumulation Method

Description of Method

The monthly accumulated precipitation RRM is calculated. The corresponding normal monthly accumulated precipitation RRM' is retrieved form the climate data base.

Corresponding accumulated value at three neighbour stations are RRMn1, RRMn2, RRMn3. Corresponding reference accumulated value at three neighbour stations are RRMn'1, RRMn'2, RRMn'3.

An error is detected when

| RRM - RRM' | > tol1

and at least two of the three following inequalities are satisfied

| RRMn1 - RRMn'1 | < tol1

| RRMn2 - RRMn'2 | < tol1

| RRMn3 - RRMn'3 | < tol1

where tol1 is a tolerance value.
