Abstract

<abstract abstract-type="main" id="grl51683-abs-0001"> <title>Abstract</title> <p id="grl51683-para-0001">Interplanetary scintillation (IPS) observations are useful to remotely sense the inner heliosphere. We present a new technique to analyze IPS observations using a wavelet transform (WT) function. This technique allows us to derive, in a straightforward way, a simple method to obtain the scintillation index (<italic>m</italic>). We tested this WT technique to analyze IPS observations obtained by the Solar‐Terrestrial Environment Laboratory (STEL) radio telescope. The analysis of the <italic>m</italic> index of the radio source 3C48 detected by STEL over the year 2012 shows the expected decrease with solar elongation reported in previous studies. The WT technique has a great potential for future solar wind studies using IPS observations from contemporary radio telescopes.</p> </abstract>
