About Tashkent Index
Our Mission
Tashkent Index was founded to provide accessible, accurate, and actionable information about air quality and ultraviolet radiation levels in Tashkent, Uzbekistan. We believe that environmental health data should be understandable to everyone—not just scientists and policymakers—and that informed individuals can make better decisions to protect themselves, their families, and their communities.
Air pollution and UV exposure are significant public health challenges in many urban areas, including Tashkent. Yet environmental data is often presented in technical formats that are difficult for non-specialists to interpret. Tashkent Index bridges this gap by translating complex measurements into clear explanations, practical guidance, and visual tools that empower residents and visitors to take protective action.
Our work is guided by principles of transparency, scientific integrity, and public service. We do not sell products, promote commercial interests, or accept advertising. Our sole focus is providing reliable environmental health information that serves the public good.
Why Tashkent Index Exists
Tashkent, the capital and largest city of Uzbekistan, faces environmental challenges common to rapidly growing urban centers: vehicle emissions, industrial pollution, construction dust, and seasonal meteorological conditions that trap pollutants near the surface. At the same time, Tashkent's geographic location and altitude contribute to elevated ultraviolet radiation levels, particularly during summer months.
While government agencies and international organizations monitor air quality and UV levels, accessing and interpreting this data can be challenging for ordinary citizens. Language barriers, technical jargon, and fragmented information sources create obstacles to understanding. Tashkent Index consolidates data from multiple sources, applies internationally recognized interpretation frameworks, and presents information in accessible formats.
We recognize that environmental awareness is only the first step. Effective public health protection requires not just data, but context: What does an AQI of 120 mean for my morning jog? Should I keep my children indoors? Is it safe to open windows for ventilation? Tashkent Index answers these practical questions, helping people integrate environmental data into daily decision-making.
How Tashkent Index Works
Tashkent Index synthesizes information from multiple conceptual sources including government monitoring networks, international air quality databases, satellite observations, and meteorological services. We do not operate our own sensor network; instead, we aggregate, interpret, and present publicly available data using standardized methodologies aligned with World Health Organization guidelines and US Environmental Protection Agency protocols.
Our interpretation process involves several steps. First, we collect raw pollutant concentration data (PM2.5, PM10, ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide) from monitoring stations. Second, we convert these concentrations to Air Quality Index values using established formulas that account for health risk thresholds. Third, we contextualize the data with meteorological information (wind, humidity, temperature, pressure) that affects pollutant dispersion and human exposure.
For UV index, we incorporate solar zenith angle calculations, ozone layer thickness estimates, cloud cover observations, and surface reflectivity factors. We present both current conditions and short-term forecasts when available, always clearly distinguishing between measured data and predictive models. We update our content regularly, though update frequency depends on upstream data availability—typically hourly for air quality and daily for UV forecasts.
It is important to note that we do not make real-time claims. Environmental measurements involve inherent delays due to data collection, transmission, validation, and processing. What we present as "current" conditions may reflect measurements from 15 minutes to several hours prior. Users should understand these limitations and use our information as general guidance rather than instantaneous precision.
Editorial Policy and Standards
Tashkent Index maintains strict editorial standards to ensure accuracy, objectivity, and reliability. Our content is developed by individuals with backgrounds in environmental science, public health, and science communication. All interpretations and recommendations are based on peer-reviewed research, official guidelines from authoritative organizations (WHO, EPA, Health Canada), and established scientific consensus.
We clearly distinguish between factual data, scientific interpretation, and practical recommendations. When uncertainty exists—as it often does in environmental science—we acknowledge it explicitly. We avoid sensationalism, alarmism, and oversimplification. Our goal is to inform, not to frighten or mislead.
We do not accept funding from commercial entities, political organizations, or advocacy groups that could create conflicts of interest. Tashkent Index is an independent, non-commercial project. We do not sell products, promote specific brands of air purifiers or masks, or receive compensation for external links. All authoritative links are provided solely for educational purposes.
We welcome feedback, corrections, and suggestions from users. If you identify an error, outdated information, or unclear explanation, please contact us. We are committed to continuous improvement and responsive to community input.
Data Sources and Verification
Tashkent Index relies on data from reputable sources including national environmental agencies, international monitoring networks such as OpenAQ, satellite-based observations from NASA and ESA, and meteorological services. We prioritize sources that follow quality assurance protocols, publish methodology documentation, and undergo peer review or independent auditing.
We verify data consistency by cross-referencing multiple sources when possible. If discrepancies arise—for example, if two monitoring stations report significantly different AQI values—we investigate potential causes (sensor malfunction, hyper-local pollution events, data transmission errors) and present the most reliable information with appropriate caveats.
We maintain records of data sources, calculation methods, and interpretation frameworks. This documentation ensures reproducibility and allows users to trace our conclusions back to original data. Transparency is fundamental to scientific integrity and public trust.
We also acknowledge the limitations of available data. Monitoring station coverage in Tashkent may be sparse compared to cities in North America or Europe. Sensor calibration and maintenance standards may vary. Satellite observations provide broad spatial coverage but lower temporal resolution. We work within these constraints, clearly communicating uncertainty and encouraging users to combine our information with personal observations and local knowledge.
Contact and Collaboration
We welcome inquiries, feedback, and collaboration opportunities. If you have questions about our methodology, suggestions for improving our content, or proposals for partnerships that align with our mission, please reach out to us at contact@tashkentindex.org.
We are particularly interested in connecting with local environmental organizations, public health agencies, educational institutions, and community groups working to improve air quality and environmental health in Tashkent and Uzbekistan. Collaborative efforts amplify impact and ensure that information reaches those who need it most.
For media inquiries, please include your publication name, deadline, and specific questions. We aim to respond to all inquiries within 48 hours, though response times may vary during periods of high demand or environmental events (such as severe pollution episodes or public health emergencies).

The Team Behind Tashkent Index
Tashkent Index is developed and maintained by a small team of environmental scientists, public health professionals, and web developers who share a commitment to making environmental data accessible and actionable. Our team members bring expertise in atmospheric science, epidemiology, data visualization, and science communication.
While we work remotely and collaboratively, our connection to Tashkent is personal. Some team members are Tashkent residents who experience air quality challenges firsthand. Others have family ties to Uzbekistan or professional experience working on Central Asian environmental issues. All of us are motivated by the belief that access to reliable environmental information is a fundamental component of public health and environmental justice.
We operate as a volunteer-driven project, dedicating time outside of our primary employment to develop and maintain this resource. As the project grows, we hope to secure grant funding from non-commercial sources (academic institutions, public health foundations, environmental NGOs) to expand our capabilities, improve data coverage, and develop additional tools such as mobile applications and community monitoring programs.
