CSIR-AMPRI CELEBRATED 46TH FOUNDATION DAY WITH TRANSFER OF INDIGENOUS SODAR SYSTEM TECHNOLOGY TO INDUSTRY

1. At a Glance

CSIR-AMPRI (Advanced Materials and Processes Research Institute), Bhopal, a constituent lab of Council of Scientific and Industrial Research (CSIR), marked its 46th Foundation Day (May 12-14, 2026) by transferring its indigenous SODAR (Sound Detection and Ranging) technology to M/s Meteoxperts Solutions Pvt. Ltd., Noida [S1][S2].
SODAR is an acoustic remote-sensing system that profiles the Atmospheric Boundary Layer (ABL) — wind, temperature, turbulence — for weather forecasting, aviation, and pollution monitoring [S2].
Exemplifies the lab-to-industry (Technology Transfer) model under Atmanirbhar Bharat, reducing import dependence in environmental monitoring instruments [S2].

On 12 May 2026, CSIR-AMPRI formally transferred SODAR technology to a private industry partner during its Foundation Day in the presence of Dr. N. Kalaiselvi, DG-CSIR & Secretary, DSIR [S1].
Precedes earlier deployment: a CSIR-AMPRI SODAR facility was inaugurated at IMD, New Delhi, on 26 September 2025 [S3].

CSIR-AMPRI established 1980 in Bhopal (46th Foundation Day in 2026 implies founding year 1980) [S1].
Parent body CSIR founded 1942, under Ministry of Science & Technology (DSIR) [S1].
SODAR concept globally dates from 1960s acoustic-radar work; CSIR-AMPRI's indigenous version was scaled up after pilot deployments and culminated in IMD inauguration (Sept 2025) → industry transfer (May 2026) [S2][S3].

Institute: CSIR-AMPRI, Bhopal (Madhya Pradesh) [S1].
Parent: Council of Scientific and Industrial Research (CSIR) — under Department of Scientific and Industrial Research (DSIR), Ministry of Science & Technology [S1].
DG-CSIR & Secretary DSIR: Dr. N. Kalaiselvi (first woman DG-CSIR) [S1].
Director, CSIR-AMPRI: Dr. Thallada Bhaskar [S1].
Technology Recipient: M/s Meteoxperts Solutions Pvt. Ltd., Noida (Director: Mr. Siddharth Gupta) [S1].
Foundation Day: 12 May 2026 (46th); celebrations May 12-14, 2026 [S1].
SODAR: Sound Detection And Ranging — acoustic analogue of SONAR/RADAR; emits sound pulses upward, analyses echoes scattered by atmospheric temperature fluctuations [S2].
Measurement domain: Atmospheric Boundary Layer (ABL) up to several hundred metres above surface; provides wind profile, thermal structure, turbulence [S2].

Scientific/Technological:
Indigenous design with compact, rugged, cost-effective build; advanced signal processing & real-time visualisation [S2].
Functions akin to SONAR but in atmosphere; complements RADAR/LIDAR in meteorology [S2].
Economic:
Reduces costly imports of foreign atmospheric profilers; opens market in airports, industrial zones, urban air-quality networks [S2].
Showcases CSIR's licensing/technology-transfer (ToT) revenue model linking PSU/private industry to public R&D [S1].
Environmental:
Supports stack plume monitoring, urban smog forecasting, and dust-storm/fog early warning — feeds into National Clean Air Programme (NCAP) style interventions [S2].
Administrative/Governance:
Embodies the lab-to-land mandate of CSIR's 2030 Vision; aligns with Anusandhan National Research Foundation (ANRF) push for translational research [S1].
Strategic (Atmanirbharta):
Cuts foreign dependence in critical met-instrumentation used by IMD, aviation, defence ranges [S2].

26 Sept 2025: SODAR facility inaugurated at IMD HQ, New Delhi [S3].
12 May 2026: Technology transfer to Meteoxperts Solutions at CSIR-AMPRI Foundation Day [S1].

CSIR-AMPRI is headquartered in Bhopal, Madhya Pradesh [S1].
CSIR-AMPRI is a constituent laboratory of CSIR, which is under DSIR, Ministry of Science & Technology [S1].
Dr. N. Kalaiselvi is the current DG-CSIR & Secretary DSIR [S1].
SODAR = Sound Detection And Ranging — an acoustic (not electromagnetic) remote-sensing system [S2].
SODAR profiles the Atmospheric Boundary Layer (ABL) — wind, temperature, turbulence [S2].
Working principle: scattering of upward acoustic pulses by temperature inhomogeneities in the atmosphere [S2].
Range: up to several hundred metres above ground [S2].
Industry partner for ToT: M/s Meteoxperts Solutions Pvt. Ltd., Noida [S1].
CSIR-AMPRI SODAR was first inaugurated at IMD, New Delhi on 26 Sept 2025 [S3].
CSIR was established in 1942; AMPRI's 46th Foundation Day in 2026 → AMPRI founded 1980 [S1].
Applications include airports, industrial zones, urban air-quality, dust-storm/fog early warning [S2].
Director of CSIR-AMPRI: Dr. Thallada Bhaskar [S1].

GS-III — Science & Technology: Indigenisation of technology; developments in S&T and their applications; Awareness in space, IT, biotech.
GS-III — Environment: Air pollution monitoring and early warning systems.
Possible question stems: 1. "Indigenous atmospheric remote-sensing instruments are critical for both air-quality management and aviation safety. Discuss with reference to recent CSIR initiatives." 2. "Examine the role of CSIR's lab-to-industry technology transfer mechanism in advancing Atmanirbhar Bharat." 3. "Compare SODAR, RADAR and LIDAR as atmospheric profiling tools and discuss their relevance to India's weather services."

CSIR & its 37 laboratories — institutional architecture of Indian S&T.
India Meteorological Department (IMD) — primary user; under MoES.
Anusandhan National Research Foundation (ANRF), 2023 — overarching research-funding shift.
National Clean Air Programme (NCAP) — policy link to urban air monitoring.
DRDO LIDAR / ISRO atmospheric science missions — comparator instrumentation.
Atmospheric Boundary Layer (ABL) — geography/meteorology concept.
Atmanirbhar Bharat & Make-in-India — industrial policy frame.
DSIR Technology Development Programmes / NewGen IEDC — translational R&D schemes.

CSIR-AMPRI is under DSIR / Ministry of S&T, NOT under MoES (which houses IMD).
SODAR ≠ SONAR: SODAR works in the atmosphere (air), SONAR in water; both are acoustic.
AMPRI is in Bhopal, not Hyderabad (which hosts CSIR-IICT/CCMB) or Pune.
SODAR uses sound waves, while RADAR uses radio waves and LIDAR uses laser/light — easy mix-up.
Dr. N. Kalaiselvi heads CSIR + DSIR simultaneously; she is not Principal Scientific Adviser.
