Subject: | TWP/SMET/C1 - Reprocess: Tipping bucket rain gauge added |
DataStreams: | twpsmet60sC1.b1 |
Description: | A tipping bucket rain gauge was added to the TWP.C1 SMET suite of instruments on 20061017. Effective 20060926, two new variables (count and rain amount) were added to the end of the twpsmet60sC1.b1 datastream. Between 9/26 and 10/17, the data for these two variables are filled with zeros. Users should not use the data during this period as the zeros are not representative of the rain fall at the site. When reprocessing of this datastream occurs these variables will be added for the 19961009-20060926 and data from 19961009-20061017 will be filled with -9999 (missing). |

Subject: | TWP/SKYRAD/C3 - NIP Failure |
DataStreams: | twpskyrad20sC3.a0, twpskyrad60sC3.b1 |
Description: | Skyrad normal incident shortwave irradiance (NIP) started reporting impossible values for direct normal irradiance starting 16 November approx 2100GMT corresponding to a rain event at the same time. The NIP was replaced fixing the problem. Direct normal data are not recoverable. However, the NIP data can be calculated from the global hemsipherical shortwave and global hemispherical diffuse datastreams by using the following relationship: Global Horizontal = Direct Normal x cos(Z) + Diffuse Horizontal where Z is the zenith angle. |
