Produk MOD11A1 V6.1 memberikan nilai suhu permukaan daratan (LST) dan emisivitas harian dalam petak 1200 x 1200 kilometer. Nilai
suhu berasal dari produk MOD11_L2. Di atas
30 derajat lintang, beberapa piksel mungkin memiliki beberapa pengamatan
jika kriteria langit cerah terpenuhi. Jika hal ini terjadi, nilai piksel adalah rata-rata dari semua pengamatan yang memenuhi syarat. Disediakan
bersama dengan rentang suhu permukaan siang dan malam
serta lapisan indikator kualitasnya adalah rentang MODIS 31 dan
32 serta enam lapisan observasi.
