वर्षप्रमाणे ऊलोपः च अस्य अन्यतरस्याम्
Pāṇini leaves out words that carry over from earlier sūtras. Expand to see the rule as a reader actually understands it.
अस्य → ऊलोपः / वर्षप्रमाणे अन्यतरस्याम्
Replace asya with ūlopaḥ when varṣapramāṇe anyatarasyām follows. Inherited words (anuvṛtti) may add further conditions.
Commentary
The affix णमुल् comes after the verb पुर् 'to fill' when the word so formed expresses a measure of rainfall and optionally the long ऊ of this पुर् is elided.
Thus गोष्पदपूरं or गोष्पदप्रं वृष्टो देवः 'it rained filling up small puddles (lit. the impression made by the foot of the cow on the soil)'. सीतापूरं or सीताप्रं वृष्टो देवः 'it rained filling up all furrows'.
Why have we used the word अस्य 'of this pur' in the sutra ? The long ऊ of पूर् is to be elided, and not the long ऊ, if there be any, of the upapada. Thus मूषिकाबिलपूरं or मूषिकाबिलप्रं वृष्टो देवः । Here the long ऊ of मू is not shortened.
