A new sensor for measuring ground top layer temperature profile was formed as a row of 40 thermistor segments connected in series, with which the change of temperature in the soil is mesaured and placed on 550 mm depth. The temperature sensor is multiple protected of humidity, calibrated on room temperature and placed vertically in the hole drilled on the lawn. The main electrical properties of the new sensor based on NTC thick film segmented thermistors are given in brief. The ground top layer temperature profile measurements were done in 40 points at 7am and 2 pm each day from the beginning of November 2017 to the end of February 2018.At the same time and in the same period of time the air temperature were measured and recorded. The results of measurements of ground top layer temperatureT(t,z) were given in daily and monthly diagrams as a function of time t and ground deepness d on z-axis. The correlation between ground top layer temperature profile and air temperature was analyzed: ...changes of ground temperature gradient and effect of precipitations on ground temperature profile. The results obtained enable study of temperature regime of ground top layer.
Novi senzor temperaturnog profila gornjeg sloja zemlje, formiran je kao niz od 40 termistorskih segmenata redno vezanih, kojim se meri promena temperature, u zemlji do dubine d=550 mm. Temperaturni senzor je višestruko zaštićen od vlage, kalibrisan na sobnoj temperaturi i postavljen u vertikalno izbušenu rupu na travnjaku. Osnovne električne karakteristike novog senzora na bazi NTC debeloslojnih segmentiranih termistora date su ukratko. Merenje temperaturnog profila gornjeg sloja zemlje u 40 tačaka vršeno je u 7 i u 14 časova od početka novembra 2017. do kraja februara 2018. godine.

Rezultati merenja temperature gornjeg sloja zemlje T(t,z) prikazani su dijagramima sa dnevnim i mesečnim pregledom kao funkcija vremena t i dubine zemlje d po z-osi. Analizirana je korelacija između temperature gornjeg sloja zemlje i vazduha: promena gradijenta temperature tla i uticaj padavina na temperaturni profil. Dobijeni rezultati omoguć...avaju dalje proučavanje temperaturnog režima gornjeg sloja zemlje.
