The phrase "ascending grade" is correct and usable in written English.
It can be used to describe a slope or incline that increases in elevation or difficulty, often in contexts like education, construction, or physical geography.
Example: "The hiking trail features an ascending grade that challenges even the most experienced trekkers."
Alternatives: "increasing slope" or "rising gradient".
Ascending grade decreases the SSD, and descending grade increases the SSD.
