Reserved Values
The values -999, -888, -777 and -666 are reserved throughout the whole API. If you receive any of these values, the data is either not applicable or not available:
| Value | Meaning |
|---|---|
| -999: | data is not available (this rarely occurs, if so, try another source) |
| -888: | parameter specific reserved value (check the description of the corresponding parameter, e.g. sunset if the sun does not set at the queried location and time) |
| -777: | parameter specific reserved value (check the description of the corresponding parameter, e.g. sunrise if the sun does not rise at the queried location and time) |
| -666: | data not applicable (e.g. cloud top temperature if there are no clouds) |
These invalid reserved values are plotted transparent in image formats.
