Earthnet Programme Office Heat Capacity Mapping Mission (HCMM) Data, ESA/ESRINEntry ID: EPO-HCMM
Abstract: The Heat Capacity Mapping Radiometer (HCMR) provide visible and thermal infrared day/night visible and IR data with a spatial resolution (at nadir) of approximately 500m for the visible channel (0.55-1.1 micrometers) and 600m for the infrared channel (10.5-12.5 micrometers). The HCMR flew on board the Heat Capacity Mapping Mission (HCMM) from 1978 to 1980. Data collected from this mission, and ... derived thermal inertia products are useful for a variety earth science studies including:
* discrimination of rock types and mineral
* measuring plant canopy temperatures;
* measuring soil temperature cycles;
* mapping natural and man-made thermal
* mapping and monitoring snow fields.
The HCMM local times of equator crossing were 2pm (ascending node) and 2am (descending node). This provided day/night coverage about once every 16 days at approximately 12-hour intervals depending on latitude. The Earthnet Programme Office archive was acquired and processed by the French Space Meteorology Centre (CMS) at Lannion (Brittany). Areas covered by this receiving station include western Europe and north western Africa.
Due to the closure of Lannion HCMM production chain and the transfer of CCT data files to ESA EPO, at the end of 1985, only copies of existing data products (raw or S/C) are available:
Code 4401 Copy of archived HCMM data and products, per CCT
Note: an archived tape contains one or more of the
a) Raw data Day (VIS or IR) or Night (IR)
b) Radiometrically corrected data
c) Radiometrically and geometrically corrected
data Day (VIS or IR)
or Night (IR)
d) Night IR pass registered on Day Image
e) Temperature difference image (Night IR
minus D IR)
f) Thermal Inertia Map computed from N/D
registered data as a function
of temperature difference image.
Note: Each tape product of a) and b) contains up to 6 min. of data. Each product of c), d), e), f) contains 2 min. of data corresponding to areas identified by numbers from 1 to 7. Each number refers to different ranges latitude, as follows:
number min.lat. max.lat.
1 26.8 34.3
2 34.3 41.6
3 37.3 46.0
4 43.7 50.9
5 48.7 56.0
6 56.0 63.0
7 63.0 70.0
HCMM data for a larger coverage area are available from the National Space Science Data Center.
