A forward estimate of mango (Mangifera indica L.) harvest timing is required for farm management (e.g., organization labour and marketing). This can be based on accumulated growing degree days (GDD) from an early stage flowering to fruit maturity, with maturity judged a destructive assessment flesh colour dry matter content. The current study was undertaken improve GDD targets Australian cultiv...
Degree-day factors are widely used to estimate snowmelt runoff in operational hydrological models. Usually, they are calibrated on observed runoff, and sometimes on satellite snow cover data. In this paper, we propose a new method for estimating the snowmelt degree-day factor (DDFS) directly from MODIS snow covered area (SCA) and ground-based snow depth data without calibration. Subcatchment sn...
In this study, in order to study the base temperature (minimum temperature for plant growth) at the degree of growth day (GDD), which is one of the important parameters in calculating the degree of growth day, first, the data required for the 2009-2017 statistical period of wheat production at the station Sararood was taken from the station. Then, after sorting and separating growth different s...
