10-minute sum of station observations of downwelling longwave radiation in J/cm² for Germany

These data come from DWD stations and legally and qualitatively equivalent partner stations operated for climatological and climate related applications. Extensive station metadata (station relocations, instrument changes, change of reference time, changes in algorithms) are provided with the download via the CDC portal. The measurements are assigned to a timestamp in UTC which marks the end of the 10-minute interval.


The solar incoming radiation includes the direct and the diffuse part of the solar radiation with respect to the horizontal plane. It is sometimes also referred to as "shortwave", including the solar spectrum up to 2.8 micron, as opposed to "longwave", which refers to the thermal radiation of the atmosphere.

Specific usage

Data sets with quality level QN=1 may contain significant errors. Users have to decide whether for their particular application the more error prone 10-minute data should be used or rather the higher quality data (hourly or daily values). When investigating long term changes or trends, consider the station specific metadata.
User determined limitations
considerations
Specific usage

The stations in the DWD monitoring networks are set up and operated according to WMO regulations.

Stations in the equivalent partner networks may deviate from WMO regulations.

Depending on the application, local, regional and influences changing with time should be considered, which can be location- and parameter specific.

Sources of long-term uncertainty are:

- changes in station height when station was re-located

- changes in instrumentation

- varying quality control procedures (Behrendt et al., 2011)

- errors during data transfer or errors in the software

- change of observing personnel

- and others (Freydank, 2014)

Conformance result

Explanation

Procedures of quality assurance are explained in Kaspar et al., 2013: several steps of quality control, automated quality control based on the software QualiMET (see Spengler, 2002) for completeness, temporal and spatial consistency, and against statistical thresholds have been applied from 2003 onwards. Corrections in the high resolution recordings are routinely passed on to aggregated values (i.e., the hourly and daily values). Some doubtful values might still exist, especially in data before 2009. No homogenization has been carried out.

Name of measure
quality_level
Measure description

The QUALITAETS_NIVEAU (QN) shows the quality control procedure applied for a data report (of several parameters) for a certain reporting time.


Data before and including 1980 can reach as best quality check level QN=5. Data after 1980 can reach QN=10 as best quality check level.

Conformance result

Explanation

QN = 1 : only formal control;

QN = 2 : controlled with individually defined criteria;

QN = 3 : automatic control and correction;

QN = 5 : historic, subjective procedures;

QN = 7 : second control done, before correction;

QN = 8 : quality control outside ROUTINE;

QN = 9 : not all parameters corrected;

QN = 10 : quality control finished, all corrections finished.
Pass
Yes

Conceptual consistency

Name of measure
quality_byte
Measure description

The QUALITAETS_BYTE (QB) denotes whether the value was objected to and/or corrected.

Conformance result

Explanation

QB = 0 : denotes not flagged,

QB = 1 : had no objections (either checked and not objected, or not checked and not objected, this can be interpreted only when considering QN);

QB = 2 : corrected;

QB = 3 : confirmed with objection rejected;

QB = 4 : added or calculated;

QB = 5 : objected;

QB = 6 : only formally checked;

QB = 7 : formal objection;

QB = -999 : quality flag does not exist.
Pass
Yes
