💧 topic_evapotranspiration(1) — GRASS GIS User's Manual 💧

hiiii bestie, you found the topic_evapotranspiration(1) page of the GRASS GIS User's Manual and honestly? iconic. it's a whole topic index, which basically means it's the group chat roster of every module that does evapotranspiration stuff. let's get into it 🫶

🌸 Topic: evapotranspiration 🌸

okay so this whole page is about evapotranspiration — and here's every module that lives under that vibe. no cap, these are the main characters:

• i.evapo.mh — does the evapotranspiration calculation the Hargreaves way, either the modified formulation or the original one, from 2001. both versions, she contains multitudes 💅
• i.evapo.pm — computes potential evapotranspiration with the hourly Penman-Monteith method. hourly!! she's precise like that ✨
• i.evapo.pt — computes evapotranspiration using the Priestley and Taylor formulation, 1972. vintage but make it slay 🌈
• i.evapo.time — does temporal integration of satellite ET actual (ETa), following the daily ET reference (ETo) from meteorological station(s). basically it's the matchmaker between your satellite data and your weather station data 🦋

also bestie, if you want even more reading material: see the corresponding keyword evapotranspiration for additional references. iykyk 📚

lowkey the whole GRASS dev team ate with this one. every single module above, catalogued, no crumbs left behind. periodt 💖

and that's the page!! ily, go compute some evapotranspiration, and remember — this was all brought to you by the © 2003-2025 GRASS Development Team, from the GRASS GIS 8.4.2 Reference Manual, and yes, GRASS 8.4.2 is the version doing all of this. mwah 💋✨👑
