Subject: | TWP/SKYRAD/C3 - NIP instrument failure |
DataStreams: | twpskyradC3.00, twpskyrad60sC3.b1, twpskyrad20sC3.a0 |
Description: | The NIP (Short Direct Normal) was replaced after it displayed symptoms of failure associated with either unknown precipitation related issues or a possible lightning strike. NIP data are not recoverable. Direct normal data can be reconstructed from global hemispheric and global diffuse data using the following relationship: global hemispheric = direct*cos(sza) + diffuse hemispheric |
Suggestions: | Disregard NIP data. |
