Find urban sequencing studies quickly
Search BioProjects, cities, countries, assay classes, and sequencing centers with a dedicated explorer designed for public urban environmental omics records.
UMDB turns public repository metadata into a browsable and downloadable resource for urban metagenomics and related environmental sequencing studies. It combines BioProject-level search, SRR-level provenance, database summaries, geography views, and cohort export workflows in one public release.
Search BioProjects, cities, countries, assay classes, and sequencing centers with a dedicated explorer designed for public urban environmental omics records.
Use summary analytics and geographic views to understand how the current release is distributed across years, locations, assay classes, and institutions.
Export matched result sets as JSON bundles, accession lists, and raw-read download scripts so the database supports actual downstream study assembly rather than passive browsing.
The dedicated explorer page groups SRR-level records into BioProjects, supports natural-language search, and exposes project expansion, cohort bundling, and download-oriented actions.
Review release-wide counts, distribution charts, summary tables, and statistical tests that describe the current database snapshot in manuscript-friendly terms.
Explore filtered year-by-location analytics and a global country map to understand where public urban sequencing activity is concentrated within the current release.
