~R,OI?OSE.1)GRID CHARACTERISTICS

● 10X1CIequal angle resolution, wit!l nesting down to 0.50 and 0.250for land products

* Temporal binning at 10 day intmvals, 3 intervals per month:

1-1o11-2021- end of 117011tll

e Diurnal binning on 002,032,062, etc., for radiation andmeteorological products. /

e Instrument teams to generate these products from standardproducts themselves - they know how best to do it with theirdata

.

e This scheme is more or less the same as ISLSCP 1”x 1”gridconvention (S00 users so far, another 500 soon)

Notes:. “Monthly 3-hourly” refers to values that are monthly means of 3-hourly data. Thus, all the 0000Z

values for a month are averaged Inta a single value, also the 0300Z valuee, eti.. The mow-free albedo data 5et in section A i5 based on NDVI fields and a model calculation, the al-

bedo field in section D 15 baeed on ERE3Edata, and the fieldq in eection E originate from a wrveyof In-dtu work.

c The documentation for the vegetation claeq data in’ section A includes vegetation morphologicaland physiological parameter associated with each vegetation type in the 5i132 model of 5ellers etal. (in prep.).
