Spreadsheets for soil samples and CRNS data processing

The repository contains two spreadsheets (Excel) for processing soil samples and cosmic-ray neutron sensing data, respectively.

Specifically:

1. the first file is called "CRNS_SoS_v3_1.xlsm" and it can be used for processing soil samples data according to weighting functions proposed by

2. the second file is called "CRNS_PoP_v2_2.xlsm" and it can be used to correct row neutrons for atmospheric correction and to inverte the signal to soil moisture according to current state-of-the-art of CRNS method. See for details:
