The use of sola. energy is toda. widely recognized for the green tra.sition but a.so for a.dressing societa. cha.lenges a.socia.ed with the rise in globa. surfa.e tempera.ure. The design of a.photovolta.c sola. pa.el field ma. require a. understa.ding of how sola. ra.ia.ion oscilla.es with other va.ia.les or fa.tors since multiple intera.tions occur during its tra.sfer within the a.mosphere. In this study, three yea.s of the incoming shortwa.e ra.ia.ion (SWin) a.d a.r tempera.ure (Ta.r) da.a.a.quired within the “Institut de Ma.héma.iques et de Sciences Physiques” were a.a.yzed using the continuous wa.elet tra.sform to extra.t the inherent va.ia.ility of these signa.s. The underlying cha.a.teristics mea.ing the timesca.e of these va.ia.ilities a. well a. the lea.-la. rela.ionship between SWin a.d Ta.r were a.so exa.ined. With the wa.elet power spectrum, the highest va.ia.ility wa. evidenced a. the 2 - 8 ba.d period for the SWin, coinciding a.most with tha. of Ta.r. This suggests tha. these two signa.s a.e well interconnected a. this tempora. sca.e. The results obta.ned with the pha.e (∅xy) difference a.a.ysis, revea. tha. SWin lea.s Ta.r by ~ 23.5˚ on a.era.e when (0 ∅xy∅xyi.e., periods ≤ 32 da.s), Ta.r increa.es with a. increa.ing SWin since the la.s between these two signa.s ra.ge between 0.09 - 2.30 da.s. However, when looking a. their interdependence a. a.la.ger tempora. sca.e (> 32 da.s), Ta.r la.s SWin. a. increa.e in SWin might not directly imply a. increa.e in Ta.r. Overa.l, these findings give insight into complex rela.ionships a.ross sca.es between the incoming shortwa.e ra.ia.ion a.d a.r tempera.ure in a.tropica. humid region of Bénin.

Selective conversion of bioma.s into ta.geted molecules like polyols, especia.ly, from cellulosic compounds, is being widely investiga.ed a. a.susta.na.le process to produce biodiesel a.d bio- a.ditives.
