Two different shading sources: near-field from objects and horizon. The horizon shading in Lorenz et al. requires identifying clear-sky conditions (they use satellite-derived irradiance); is it reasonable to expect users...

We had imagined that pvanalytics would also contain workflows that assemble base-layer functions to accomplish some purpose. Workflows would be the analogue of the ModelChain object in pvlib-python.

> Or should there be, for example, a previous step where daytime is identified? Short answer: Yes. An explanation: The `clipping.levels` function is looking for peaks in a histogram of...

@camsilva thanks for sharing your views. I am picturing a layer of functions built on top of the basic clipping library, something in the spirit of ``` def label_clipping(data, how='method...

> thermal offset at night can be different from the daytime offset This is also the question in my mind. I have no objection in principle to adding this function,...

This business of aligning data to the timestamp (it appears that @PetersonUOregon prefers left-labeled intervals, others prefer right-labeled) suggests that maybe the implementation could be done using `Series.resample(..., label=..., closed=...)'`...

Another [paper ](https://www.sciencedirect.com/science/article/abs/pii/S0960148122016962)describing a QC method to concurrent GHI and DHI.

If the two methods (@PetersonUOregon and in the reference @AdamRJensen found) give very similar results, they could both be included in the documentation.

> Ill-considered idea: create a new package under the pvlib organization (pvlib/pvplotting?) that embraces the junk drawer mentality and has a low barrier to entry. Supporting both pvanalytics and pvlib-python?...
