Mandal Insights

What this is
One mandal at a time: its readings, satellite context, trend and where the sources agree.
What it says now
The State's 1,746 wells averaged 11.4 m below ground on 9 Sep, 3.2 m deeper than a year ago.
What to do with it
Look a mandal up before a visit or a meeting.
Prototype. Prototype results do not replace official field measurements or APWRIMS outputs.

Weekly since 25 Jun; dashed lines at 40 and 60, the drought manual’s class limits. Cropland is about 56% of this mandal's land.

Satellite index: NOAA STAR VHP, 4 km weekly, weighted to cropland (ESA WorldCover 2021). Plant vigour against the same weeks in other years, not yield.

SPI route (satellite)+0.34Near normal; would set Trigger 1 on its own route. 3.2.1 C: SPI below −1 is a deficit; below −1.5 sets Trigger 1 without a dry spell. CHIRPS v3 since 1981.
Trigger 1 set by a dry spell. Table 3.11: a dry spell sets Trigger 1. Without one, only large-deficient rainfall (or SPI below −1.5) does.
