Is there microdata for a physical quantity?

Question

Search Engine Optimization

Tell me, is it possible to somehow tell search engines the value of a certain value? In search queries to my site there is a query "water level in the river". Now the flood (still continued, but the water has already begun to subside, yes, so late) and many are interested. Water level information is published daily. The text is always the same, but the date and value change. I would like to inform the search engines that the site has an up-to-date value.
