PARLIAMENT QUESTION: COVERAGE OF DOPPLER WEATHER RADAR IN HIMACHAL PRADESH

1. At a Glance

• Doppler Weather Radar (DWR) is the backbone of IMD's nowcasting and severe-weather warning system; the Lok Sabha was informed (05 Feb 2026) that 3 DWRs operate in Himachal Pradesh — Kufri, Jot, Murari Devi — within a national fleet of 47 DWRs covering 87% of India's area [1].
• Examinable as a GS-III (Disaster Management / Science & Tech) topic linked to Mission Mausam, Himalayan cloudbursts, and the Common Alerting Protocol (CAP)–SACHET alert pipeline [1][2].

2. Why in the News

• PIB release dated 05 Feb 2026 by the Ministry of Earth Sciences (MoES) answering a Parliament Question on DWR coverage in Himachal Pradesh after recurrent cloudbursts/flash floods in the state [1].
• Tied to ongoing rollout of Mission Mausam (launched Sep 2024) which targets a major expansion of the radar network by 2026 [2][3].

3. Background & Evolution

• 2014: India had only 14 operational DWRs; network has since grown ~250% to 50 units announced by Dr Jitendra Singh [3].
• 10 DWRs in the Western Himalayan Region progressively installed at Leh, Banihal Top, Jammu, Srinagar, Lansdowne, Mukteshwar, Surkanda Devi, Jot, Murari Devi, Kufri [4].
• Jot & Murari Devi DWRs jointly inaugurated by Union Minister Dr Jitendra Singh and HP CM Sukhvinder Singh Sukhu [4].
• Sep 2024: Mission Mausam launched with ₹2,000 crore outlay to make India "Weather-ready & Climate-smart" [2].

4. Core Static Facts

• Implementing Ministry: Ministry of Earth Sciences (MoES); executing agency India Meteorological Department (IMD) [1].
• National DWR count: 47 operational; area coverage 87% of India [1].
• Himachal Pradesh DWRs (3): Kufri, Jot, Murari Devi [1].
• Mission Mausam outlay: ₹2,000 crore; horizon 2026 [2].
• Mission Mausam infra targets: 50 DWRs, 60 Radiosonde/Radio Wind stations, 100 disdrometers, 10 wind profilers, 25 radiometers, 1 Urban Testbed, 1 Ocean Research Station, 10 Marine AWS [2].
• Alerting stack: Common Alerting Protocol (CAP) disseminated via the SACHET platform; warnings routed through State Emergency Operation Centres (SEOCs) [1].

5. Multi-Dimensional Analysis

Scientific / Technological

• DWRs measure precipitation intensity + radial velocity, enabling nowcasting (0–3 hr forecasts) of heavy rainfall, hailstorms, thunderstorms, snowfall [4].
• Mix of S-Band, C-Band, X-Band radars; X-Band preferred for Himalayan and NE terrain due to portability and short-range high resolution [4].

Administrative / Disaster Management

• IMD pushes CAP alerts → SEOCs → district authorities → citizens; integrates with NDMA workflows [1].
• Mountain terrain creates radar shadow zones, justifying dense X-Band network in HP/Uttarakhand/J&K/NE [4].

Environmental / Climate

• Mission Mausam explicitly framed as a climate-change adaptation tool for extreme weather events [1][2].

Federal

• Centre installs/operates DWRs; states (HP SEOC) handle last-mile dissemination — classic cooperative federalism on disaster risk reduction [1].

6. Recent Developments (last 12-18 months)

• Sep 2024: Mission Mausam launched (₹2,000 cr) [2].
• 2024–25: Announcement of 10 X-Band DWRs for Northeast India and Himachal Pradesh [4].
• 2025: DWR network expanded to 50 units (from 14 in 2014) [3].
• 05 Feb 2026: Parliament informed of 47 operational DWRs and 3 in HP [1].

7. Prelims Hooks

• Mission Mausam is a scheme of the Ministry of Earth Sciences, NOT MoEFCC [2].
• Mission Mausam outlay: ₹2,000 crore [2].
• Mission Mausam launched in September 2024 [2].
• 47 DWRs operational nationally as of Feb 2026, covering 87% of India's area [1].
• DWRs in Himachal Pradesh: Kufri, Jot, Murari Devi (3 sites) [1].
• CAP = Common Alerting Protocol; disseminated through SACHET platform [1].
• 10 DWRs cover the Western Himalayan Region [4].
• DWR count grew from 14 (2014) → 50 (2025) [3].
• Mission Mausam targets include 60 Radiosonde stations and 10 wind profilers [2].
• IMD is the executing agency; CAP alerts routed via State Emergency Operation Centres (SEOCs) [1].

8. Mains Relevance

• GS-III — Disaster Management; Science & Technology applications in everyday life.
• GS-I — Geography (Himalayan extreme weather, cloudbursts).
• Possible question stems: 1. "Discuss how Mission Mausam strengthens India's preparedness against extreme weather events in the Himalayan region." 2. "Examine the role of Doppler Weather Radars and CAP-based dissemination in last-mile disaster warning. What gaps remain?" 3. "Cloudbursts in Himachal Pradesh reveal limits of conventional forecasting. Critically evaluate."

9. Related Topics to Study Next

• Mission Mausam — parent umbrella initiative [2].
• IMD's 150-year journey / modernisation — institutional context.
• NDMA & SDMA architecture — receives & acts on CAP alerts.
• Common Alerting Protocol (CAP) / SACHET — ITU-standard alert backbone.
• INSAT-3DS / Meteorological satellites (ISRO) — complementary observation.

• National Monsoon Mission, ACROSS scheme — sister MoES programmes.
• Bhuvan & NRSC disaster portals — geospatial overlap.

10. Common Errors / Trap Areas

• Ministry confusion: Mission Mausam is under MoES, not MoEFCC or MoS&T.
• Coverage figure: 87% is area covered, not population covered — wording in MCQs matters [1].
• Total count: 47 operational DWRs (Feb 2026 PQ) vs 50 announced figure (review statement) — be precise on source/date [1][3].
• HP sites: only 3 (Kufri, Jot, Murari Devi); aspirants confuse with other Himalayan sites like Mukteshwar (Uttarakhand) or Banihal (J&K) [1][4].
• CAP vs SACHET: CAP is the protocol/standard; SACHET is the platform that delivers it — not synonyms [1].
