Journal de température du compost : points et profondeur de mesure fixes, température ambiante près du tas et chaque retournement consigné
Protocole d'observation proposé pour un tas ou un bac à compost de jardin : relever un thermomètre à longue tige à des points repérés et à une profondeur indiquée, selon un calendrier fixe, mesurer simultanément la température ambiante près du tas et consigner chaque apport, retournement ou arrosage dans une ligne d'événement, pour rapprocher la hausse, le plateau et la baisse de température des interventions effectuées ; aucune température cible ni aucun résultat n'est affirmé.

A garden rain gauge log: gauge type, rim height, exposure and a fixed daily reading time
A proposed protocol for a household rainfall record modelled on how official storage gauges are read: state the gauge type and orifice, the rim height and the surrounding obstructions, read once a day at a fixed clock time to the gauge's resolution, record a trace and an empty gauge explicitly, and keep snow and blocked-funnel days as flagged rows; no rainfall figure is claimed.

An open-top garden rain gauge read once a day records a lower monthly total than an identical gauge read after each shower, and the gap is larger in warm months
Hypothesis: two identical open-top wedge gauges side by side, one read and emptied at a fixed morning hour and one read and emptied within an hour of each shower, differ in their monthly totals because water standing in the open gauge evaporates between rain and reading; the difference should grow with warm, dry, windy afternoons and shrink to near zero for funnel-and-bottle gauges. No measurement is reported.
