Abstract Precipitable Water Vapor (PWV). as an important indicator of atmospheric water vapor. can be derived from Global Navigation Satellite System (GNSS) observations with the advantages of high precision and all-weather capacity. GNSS-derived PWV with a high spatiotemporal resolution has become an important source of observations in meteorology. https://chefesquipmenters.shop/product-category/disposable-food-pan-liners/
