Kelsall model week-by-week and averaging the residual intensity values. Small-scale residual ZE structures near the ecliptic plane can be seen clearly in the ZSMA maps, in particular at mid-IR wavelengths (e.g., [@Kelsall98]). It is therefore necessary to construct a ZE model based on IR-satellite data with higher spatial resolution.

Following the completion of the IRAS and COBE/DIRBE missions, a few satellites have since conducted full-sky surveys in the IR regimes, including AKARI and the Wide-field Infrared Survey Explorer (WISE; [@Wright10]). Table \[tab:irsurveys\] offers a comparison of major full-sky mid- and far-IR satellite surveys. The Japanese satellite AKARI, a satellite dedicated to IR astronomical observations, was the third mission to survey the whole sky at mid- and far-IR wavelengths [@Murakami07]. Although most of the smooth ZE structure seen in the AKARI mid- and far-IR images can be reproduced well with the Kelsall or the Wright/Gorjian models, there are discrepancies on small scales [@Pyo10; @Kondo16]. In particular, the intensities and the ecliptic latitudes of the peak positions of the asteroidal dust bands and the MMRs cannot be precisely reproduced with these models [@Pyo10; @Doi15; @Kondo16]. The DIRBE model cannot reproduce the real fine structure of the asteroidal dust-band components, because DIRBE operated
