It is the 2nd ragam in the 7th chakra Rishi. The mnemonic name is Rishi-Sri. The mnemonic phrase is sa ra ga mi pa dha ni. Its aroha?a-avaroha?a structure is as follows
Arohana: S R1 G1 M2 P D1 N2 S'
Avarohana: S' N2 D1 P M2 G1 R1 S
The specific notes used in this scale are shuddha rishabham, shuddha gandharam, prati madhyamam, shuddha dhaivatham, kaisiki nishadham. As it is a melakarta ragam, by definition it is a sampoorna ragam. It is the prati madhyamam equivalent of Ratnangi, which is the 2nd melakarta.

Jalarnavam's notes when shifted using Graha bhedam, yields no other melakarta ragam, like all 6 ragams in the Rishi chakra (Salagam, Jhalavarali, Navaneetam, Pavani and Raghupriya being the other 5). Only these ragams have a gap of 3 notes anywhere in their scale, between G1to M2. Such a gap does not occur in any other melakarta by definition. Graha bhedam is the step taken in keeping the relative note frequencies same, while shifting the shadjam to the next note in the ragam.
