Comparison of Multi-Satellite Precipitation Data from the Global Precipitation Measurement Mission and Tropical Rainfall Measurement Mission Datasets: Seasonal and Diurnal Cycles

Table 1

Mean rain rates, diurnal precipitation amplitudes and peak times for ninxe buoys and for 5° × 5° area-averaged IMERG and TMPA data. The numbers in bold indicate the diurnal signals were detected at the 90% confidence level.
